Scheme of switching on the DRL when starting the engine. How to connect running lights

There are many options for installing DRLs on the front of the car. From my own experience I can say that if you decide to really be more noticeable on the road, then you need to put it higher. If for you DRL is just an excuse for Mr. Policeman road service, then it doesn't matter where you fix it.

Installing running lights in a car dealership when buying a new car is very expensive. I was offered to put on the Duster for 15 thousand rubles, the price of a Philips kit in the store is 3 thousand rubles. If the DRL is with a good bundle, then installation and connection will take 15-20 minutes.

Abroad they are designated as DRL - short for "Daytime Running Lights.

Types of daytime running lights

The complexity of installing daytime running lights depends on their design and the provided fixtures.

I will list the main types:

1. each LED separately, called the eye of an eagle, eagle eye, Eagle Eyes;
2. in the form of a ring resembling angel eyes;
3. in the case of fog lamps;
4. LED Strip Light installed inside the headlight.
5. classic monoblock elongated shape.

DRLs in the form of angel eyes are the rarest. Unlike ordinary ones, they have powerful LEDs and lenses that focus the light. When you turn on the dipped beam, they dim and become dimensions. Ordinary angel eyes are regularly installed on some cars in expensive trim levels and on BMW, on which they were first used. They are equipped with some bi-xenon and xenon lenses.

Rules for installing running lights

Most want to put them in such a way that they look harmoniously with the dipped headlights and high beam. Therefore, half of motorists put at the level of foglights. If you have running lights power up to 5 watts, then at a low installation they quickly collect dirt and dust, lose luminous flux by 2-3 times. Especially true on country roads with difficult terrain, the light may not be visible because of this. And in the heat hot air near asphalt, which is denser, scatters light. If you need them for their intended purpose, in order to increase the level of safety, then put them between the headlights.

The main requirements for Russia are specified in GOST R 41.48-2004 and GOST R 41.87-99. Depending on the type of vehicle, the installation parameters may vary.

1. light intensity from 400 to 800 candela for each DRL;
2. the illuminating surface area of ​​each DRL is at least 40 cm², so that powerful small LEDs are not installed.

To measure the intensity of light with your own hands, measure the illumination with a luxmeter on the optical axis from a distance of 1 meter. This way you will get Candela, not Lux.

After installing the DRL and connecting, it is necessary to check in sunny weather from 100 meters. Half of motorists, after installing Chinese junk with a power of 2 watts (brighter than dimensions), take a photo at night near the car. They take pictures at night so that at least a little light shines.

All these requirements are not invented during a feast by thumping ministers. These requirements, like other rules traffic, written in the blood of traffic accident victims.

eagle eye

The most difficult do-it-yourself DRL installation is at the eagle eye, which is usually made in the form of a bolt with a nut. Mounting requires a flat surface and drilling holes. Most often put in the bumper, placing in one line. Someone likes to drill foglight plugs so as not to spoil the banner.

After the purchase, I recommend sorting out all Chinese LED lighting equipment. This will greatly extend the service life. According to numerous reviews of the owners, due to poor assembly, once a month you will have to change the eagle eye to a new one. The LED has a very bad contact with the body, so it just overheats and burns out. Under the influence of the sand-salt mixture on our roads, they also quickly deteriorate. The reason for this is poor sealing of the case, salt corrodes conductors, and high temperature acts as a catalyst.

Mounting is of two types, threaded or latched. Sometimes there is an execution for surface mounting on double-sided tape. But the adhesive tape is different, sometimes it immediately falls off, sometimes it lasts for a year. But then they are easy to steal by tearing this garland from the bumper.

With a threaded fastening at the back, it is necessary to tighten the nut, that is, climb inside the bumper with your hand. If they burn out at least 1 piece a month, then they will have to fall under the car once a month to unscrew and tighten the nut and reconnect the wires. That's why better mount on latches.

Modular models

..

Almost everyone knows how to install daytime running lights in kit modules. This design can be placed anywhere typical schemes placements are shown in the picture below. You only need to drill holes for the bolts. There is also a mount on double-sided tape, but under the influence of salt and atmospheric conditions, they can simply fall off.

DRL from foglights

Another way to install DRL according to GOST without changing appearance auto, put it LED bulbs into the fog lights. I recommend not to install Chinese junk whose characteristics indicate a power of more than 5 watts and no cooling system. If the power of the LEDs is more than 5 watts, they will overheat and quickly die. For light bulbs without a heatsink, to explain too good parameters The Chinese writes that Cree or Osram diodes are installed. In fact, there are no Cree and Osram, these are fakes that look like real Crees. Any seller, including a Chinese, will swear and swear by his mother that they are real. I communicate with representatives Chinese factories and conduct examinations of fake KRI LEDs for domestic companies.

If you do not have regular halogen foglights, then you can purchase:

1. round DRL on places PTF;
2. LED PTF with daytime running lights;
3. just LED PTF.

Do not forget that fog lights according to GOST also have a cut-off line. When choosing LED lamps for PTF, try to keep the cut-off line. So that with your LED spotlight you don’t fuck the oncoming people in the eyes.

Some varieties for PTF

LED Strip Light

Everyone has the same story, look at the daytime running lights in the form of a tape at expensive cars and they also want to decorate their shmarovoz with their own hands. As a result, such a tape cannot perform the function of daytime running lights; from the outside it looks lousy, cheap. During the day you can only see at close range, not to mention 100 meters.

Most often they buy a car LED strip from the Chinese, who are smarter and choose a flexible LED tube, such as neon. Whoever is really bad with fantasy, they put a home tape. In any case, a powerful one requires cooling, otherwise it will quickly burn out.

Neon tube with LEDs

With the correct installation of a flexible tape or tube inside the headlight, you will get decorative lighting that will look decent. DRL from such a tube will not work, even if you try hard.

The most difficult installation option, you have to disassemble the headlight. The hardest thing to take off transparent plastic front. The headlight is sealed and the glass is put on sealant. There are two types of sealant, which soften at temperatures above 100 degrees, and which do not soften at all even at 300 degrees. I came across non-separable ones, I took one apart for 10 hours, so as not to spoil or scratch it. The sealant was checked with a soldering iron, which heated up to 300 ° and could not melt it in any way.

For heating, use an oven or a box heated building hair dryer. Once the sealant is soft, the clear plastic will peel off easily. For reassembly you can buy a special rubber sealant that xenons use.

Video headlight analysis

DRL monoblock, classic

The most common type of daytime running lights is in the form of a monoblock, an elongated square. It is optimal to install in the radiator grille, between the dipped beam headlights. It is very undesirable to put in the grill, which is located in the bumper. For example, in Duster, this grille is located between the PTF, it turns out that the running lights will be even below the level of the fogs. In fact, it depends on the type of car, the PTF of SUVs is higher due to the increased ground clearance And big wheels. In an ordinary passenger car, they are low.

Some put it on the front bumper LED headlights working light or additional. Usually they are too powerful for DRL, but the most powerful ones can do. weak models.

The Chinese sell a variety of LED lines without housings, passing them off as DRLs. indicate for them high power And low price. Motorists, delighted with the price and characteristics, begin to sculpt them on their cars. But they cannot perform the DRL function, because they shine on all sides, according to the passport 120 degrees. They should shine forward with an angle of 30 degrees, respectively, should have a reflector or a focusing lens. Without a case, they have no cooling and they die from overheating and exposure to salt on the roads.

Following the rules correct installation daytime running lights for a car according to GOST, you will really become more noticeable on the road and increase traffic safety. There are enough fools on the road even without us, so there is no need to replenish their ranks.

It is a priority for car owners in cars in which this type of optics is not installed. As you know, it is not the first year that you cannot drive on the roads of the Russian Federation without daytime running lights, for this violation the driver will have to pay a fine. detailed instructions on the topic of how to connect DRL from the generator is given below with diagrams and a detailed description.

[ Hide ]

A set of necessary tools and materials

Before connecting the DRL from the generator, it is necessary to prepare in advance all the necessary tools that may be required in the process.

For correct inclusion daytime lights you will need:

• DRL kit;
• pliers;
• 12 volt relay;
• reed switch;
• single core cable;
• insulated two-wire cable.

When all the elements and tools are collected, you can start connecting. Below we consider the main schemes that will allow you to connect optics to onboard network auto, namely to the generator unit.

Scheme 1

IN this case the navigation lights will be switched on in automatic mode immediately after the driver turns the key in the ignition. And turning off the optics, respectively, will be carried out after stopping power unit. The connection diagram is shown below. It should be borne in mind that the positive output of the optics must be connected to the ignition switch, and its negative contact - to the vehicle body, that is, to ground.

In principle, the scheme is quite simple, so even a car owner who is far from electrical engineering can cope with its implementation. The only one important point- make sure that everything is connected correctly.

Scheme 2

This option for connecting DRL can actually be called a variation of the above scheme. Only in this case, all actions, although they are almost the same, are performed with a slight difference. In particular, after the activation of the head lighting, that is, the low beam, the navigation lights will be turned off. In this case, the positive contact should be connected in the same way as in the above method, however, the negative output will need to be connected to the positive contact of the dipped beam lamps.

This approach is due to the fact that the incandescent bulb, which is used in most modern vehicles to provide low beam lighting, has a lower resistance. And through this resistance passes more than high voltage. At the moment of activation of the dipped-beam lamps, a plus is formed on the negative terminals of the daytime running lights, as a result of which the optics are automatically turned off.

It should also be noted that this option is not particularly difficult to implement. You only need to do everything in accordance with the diagram, namely, not to confuse and connect all the conclusions correctly. In the event that as parking lights Are you using incandescent bulbs? this principle connections can also be used for dimensions.

Scheme 3

Another option to ensure connectivity has more complex scheme, but it is also not particularly difficult to implement. In this case, DRL activation is carried out immediately after starting the power unit. To ensure the inclusion, a relay, a battery, as well as a generator unit will be involved. The negative output of the daytime running lights should be connected to ground, that is, the car body, and the positive output to the relay contact marked 30.

As for the relay, its contact with the label 87 must be connected to the positive terminal battery. And pin 85 for the correct connection should be shorted to ground through the optics. As for label 86, it must be connected to the reed switch to one contact, and the second to be connected to the positive output of the generator unit.

After completing these steps, you will need to start the engine and move the reed switch around the generator set so that the relay can be activated. This will help activate DRL. Next, the reed switch should be installed in a special thermopolymer and fixed on the generator. Make sure that the reed switch is fixed directly on the part of the node where the relay is triggered.

Scheme 4

This option can be called a variation of the above method, it is best suited if you do not have a reed switch. In this case, contact number 86 will need to be connected to a light bulb emergency pressure motor fluid, which is located on the control panel of the car. When implementing this method, the optics will also be activated after the motor starts, but this method is easier to perform (the author of the video is the DED channel).

What advice from experts should be taken into account when installing optics:

1. All wiring must be carefully insulated, several layers of electrical tape can be used to ensure greater reliability. Please note that in engine compartment high temperatures, respectively, this can lead to melting of the existing insulation. Moreover, an additional layer of insulation will prevent the negative impact of water on the system.
2. It is desirable to fix all wires with ties where possible. This approach will ensure better reliability wiring.
3. Use DRL only from well-known manufacturers so that you don't run into problems later. premature exit failure of the optics.
4. When installing optics, be sure to follow the installation requirements. If the installation is done incorrectly, it may cause unnecessary questions from the police. We have already written more about the requirements.
5. When buying lamps, pay attention to their body. The entire structure must be made in the most reliable way, any damage and cracks are not allowed. The glass of the lanterns must also be as strong as possible so that it does not crack at the first damage.
6. Most best option for mounting daytime running lights - in recesses on front bumper, next to the fog lights, if any. As an option, you can choose a place to install under the top of the motor radiator cross member. In any case, the main thing is that the mounting location of the optics meets the requirements.
7. If you bought a DRL average cost, then check their housing for tightness. As a rule, in inexpensive options, the tightness leaves much to be desired, and this can lead to burnout of the bulbs as a result of water getting inside the headlight.

Or DRL, are becoming more and more available and popular. Manufacturers give many arguments for their installation, including minimal fuel consumption due to lower energy consumption, long service life and high quality.

Since 2010, Russian legislation has introduced their mandatory use with the alternating inclusion of dipped beam headlights in daytime. EU regulations require DRL to be installed on all new model vehicles. Also, their installation is quite possible on older cars, thus increasing their attractiveness and safety.

The supply market for daytime running lights is extremely high and seemingly saturated similar friend on other options. The modules are so simple that even a novice amateur can install them. Meanwhile, installation is a serious matter, and before you get started, take a look at a few details that will influence your choice.

What are daytime running lights for?

With coming summer period comes relatively Better conditions driving - dry weather, long days and lots of sunshine. But it is the latter indicator that is not always the driver's allies. It often blinds, causes eye fatigue.

According to some studies, the use of daytime running lights increases the visibility of the vehicle on the road, which helps to avoid many accidents. In the EU countries, since 2011, DRLs must be installed on all manufactured cars, in Russia a year earlier it is valid, where there is a requirement to turn on the light (either fog lights, or dipped beam headlights, or daytime running lights) in daylight hours days. What is the difference between these types of automotive lighting?

On the video - installation of DRL:

Better visibility

Daytime running lights are used to increase the visibility of the vehicle during the day. Unlike low beams, they are equipped with powerful LED lights, so that the modules become more visible to other road users. In addition, these lights are designed in such a way that they are . Running lights daylight light up when you start the car, but you can only drive with them during the day. When it gets dark, you need to switch to low beam, automatically turning off the DRL.

Less fuel consumption

Another advantage of daytime running lights is their energy efficiency. They consume only 10% of the energy required for standard low beam headlights. Daytime running lights have a huge impact on fuel consumption as a single module consumes 6.8 watts, less than 14 watts in total. For comparison, one halogen lamp low beam consumes 60 watts, which is 8 times more. In addition, DRLs operate up to 10,000 hours, which is equivalent to 500,000 km of travel.

Modern design

LED technology, which is used in the production of daylights, is known as one of the most innovative and.

Self installation

Some manufacturers offer to install daytime running lights with their own hands. Such kits include:

1. Two LED modules with wires and plugs.
2. Control block.
3. Installation Components:
   • two pressure brackets;
   • long cables (6 meters);
   • simple connector;
   • bolts;
   • latches;
   • installation instructions.

But nevertheless, having installed the DRL, you need to check it in the nearest workshop.

How to install daytime running lights

Their installation is not as difficult as it might seem at first glance. To do this job, it is enough to have basic tools, such as a screwdriver. But, before deciding to build modules, you need to choose suitable model lighting.

On the video - installation of daytime running lights on a VAZ:

According to the position of the daytime running light:

1. Should automatically turn on when the device for starting or stopping the engine is in the working position.
2. Should automatically turn off when the fog lights or dipped beam headlights are turned on.
3. Front, side and rear marker lights, the side lights and the tail light will not turn on if the daytime running lights are on.
4. Must be at the front of the car, white color placed symmetrically and at the same height.
5. Must not speak for external dimensions vehicle.

DRL selection

When buying, you should carefully look at the light. Lights must be appropriately marked, which is proof of their use on the territory of Russia. Unfortunately, the cheapest kits often do not have the features required by law. The glass must have an E approval stamp along with identification number issuing country.

The reflector RL is also mandatory - indicating the version number of the rules according to which the certificate was issued, the certificate number and the name of the manufacturer. The marking must be durable, indelible and visible on the vehicle. These requirements are met by a number of daytime companies, such as Hella, Philips or Osram.

Installation height

Daytime running lights may not be installed more than 1500 mm or less than 200 mm from the ground, and the distance between them must not be less than 600 mm. If the width of the vehicle is less than 1300 mm, the distance between the lights must be 400 mm. They may also extend beyond the contour of the vehicle and must be installed 400mm from the edge of the vehicle.

System installation

What is your opinion about self installation daytime running lights?

Daytime running lights (DRL) in the headlights, fog lights, in turn signals installed separately, but wherever they are not installed. Are there any rules at all? regulate the installation of DRL? Is it possible install DRL yourself? They also say that they consume many times less energy, and therefore you save on gasoline. Everything in order..


What are DRLs and what are they for?
"Daytime running lights" have nothing to do with side lights. This new concept appeared in the rules due to the fact that they began to equip modern cars. This term refers to external lighting fixtures designed to improve the visibility of a moving vehicle in front during daylight hours. On new European cars you can often find lights in the headlights that stand out structurally in it. Most DRLs are LED bulbs. When using daytime running lights, additional light signals (fog or dipped beam) are not required.

Rules for installing DRL

Excerpt from " State standard of the Russian Federation GOST R 41.48-2004 (UNECE Regulation N 48)":

GOST R 41.87-99 (UNECE Regulation N 87). According to the rules, daylight emitters must occupy an area of ​​25 cm to 200 cm (in Russia "not less than 40 cm") and emit light with a power of 400 to 1200 cd (in Russia from 400 to 800 cd).

This standard establishes uniform provisions concerning the approval of daytime running lamps for motor vehicles.
According to this GOST, all certified running lights must have the appropriate designation.

Table 6a - Requirements of the UNECE Regulations for the presence of external lighting devices on vehicles:

• Daytime running light: White, 2 pcs.
• Recommended for categories M, N. (passenger and utility vehicles, trucks)
• Prohibited for categories O (trailers with two or more axles, trailers with a central axle and semi-trailers)

How to connect daytime running lights

DRL connection diagrams many, some of them are very simple, others require some experience with a soldering iron. All of them allow you to turn on the running lights automatically:

Scheme No. 1. Headlights turn on automatically when driving and turn off when stopped. When parking, the car is indicated by marker lights.
Such an algorithm for the operation of the outdoor lighting system fully complies with the requirements of traffic rules.
The scheme was tested on all Russian cars.
The source of information about the movement is the vehicle speed sensor
Contacts K 1.1 of the low beam headlight switch are included in the wire break from the low beam switch to terminal 85 of the RBS. (if you need to turn on the low beam on the spot, then you need to parallelize the contacts of the low beam switch).
Relay K1 - automotive, 851.3747, but any one that has a breaking pair of contacts and works stably at a voltage on the winding of 6 ... 14 V can be used. For example, RES10, passport: RS4.529.031-07.
V. Yugrin Radio №8, 2005

Scheme No. 2. Using PTF in daylight mode and automatically turning them off along with the ignition.

Disable staff scheme turn on the PTF and remake it to turn on after turning the ignition key.
Any thyristor with a permissible current of 0.3 A is suitable. A 1500 microfarad 25 Volt capacitor will produce 23 seconds. delays. Resistors should be from 0.25 W to 47 (51) and 10 kilo ohms.
It is convenient to place the circuit in the relay case by surface mounting and place it in mounting block. We also take the plus we need after the ignition switch.

Procedure:

1. Disable negative wire to power the winding of the power window relay and isolate it.
2. Find the wire going to PTF key, disable it from regular place and insert instead of disabled in paragraph 1
3. Insert finished structure into the socket.

Scheme No. 3. Turning on the PTF when starting the engine (generator).
The scheme is used on the VAZ 2110.
The headlights will turn on automatically when the generator is started. The engine is started - the generator is running - the PTFs are turned on, it does not work - vice versa.
The dimensions are turned on by the button and the ignition switch is open at the same time.
The essence of this method is to install a jumper from the power supply of the excitation winding of the generator to the PTF relay.

• We remove the tidy and do as in photo 1.
• We take out PTF button and disconnect the corner wiring from the plug photo 2.3.
• We connect it to our wire (12 on connector X1 of the device), photo 4.

Insert into free place on the plug and put the button in place.
Scheme No. 4. Implementation of DRL using low beam. The principle of operation is the same as in scheme No. 3, the dipped headlights turn on after the engine starts and turn off when it stops, while the dimensions are turned off. Everything else works as normal.
You will need two low-power diodes (1A, for example KD10) and we connect them in series. Solder wires to them. overall length about 40cm. Because the diode is polar, then they should be connected as shown in the photo.
Parsing dashboard and connect the workpiece with the 12th pin of connector X1, as in the photo (the color of the wire is yellow, but the essence is the same).
We take out the button for turning on the lighting and connect the second end of our workpiece to the green wire of the connector. Or insert the stripped wire into the socket of the connector. We insert the button into place and check the performance.

If you need to stand with the dimensions when the engine is running without dipped headlights, then we put the button in the cut of the wire.
Scheme No. 5. Automatic on/off daylight by on/off generator.
The schemes were tested on Lada Priora and VAZ 2110.

1. The first scheme - if only the work of the generator and the handbrake is tied.
2. The second circuit contains another transistor that turns off the DRL when the dimensions or headlights are turned on by supplying "+" to the base of the KT814 transistor.
3. The third scheme of Roman Toropov. It cancels the DRL under the following conditions: The handbrake is raised (for autostarting the internal combustion engine from an alarm or parking with the internal combustion engine running) and for turning on the dimensions (transferring to the normal operation mode of the headlights or PTF). In other words, under these conditions, "automatic activation of DRL" is disabled when the generator is started. This DRL scheme, which passed the TRP.

Scheme No. 6. Auto-turn on DRL when starting the engine and turn off from the dimensions / dipped beam. (oil level sensor)
The scheme was tested on the VAZ 2110.
IN this option the engine operation signal is taken from the minimum oil pressure sensor (from the instrument panel block). Running lights turn off if you turn on the dimensions or dipped beam.
PTF or dipped beam can be used as running lights.

Scheme No. 7. Automatic inclusion of DRL when the engine is started, and work at half strength when turning on PTF or near.
The scheme was tested on the VAZ 2110.
When the engine (generator) is started, the DRL lights up. When the dimensions are turned on, the work of the DRL continues, and when the PTF or dipped beam is turned on, the DRL begins to shine at half strength. This is due to the switching of relay 2 when the circuit is energized when the PTF or dipped is turned on. And also due to the resistor, which we have in front of the DRL on the excitation wires from the PTF and the neighbor. We use a diode so that the power of one device does not flow into another device.
Scheme No. 8. The inclusion of DRL after starting the engine after 7 seconds. Goes out when switched on.
The scheme was tested on the VAZ 2110.
When the engine is turned off, the running lights go out. There is no additional load at the factory. When blinking high beam, DRLs do not go out.

For example, the button is located in the console next to the heater control unit. This is a manual shutdown. We hook the assembled circuit to the clips to the fuse box. It is convenient to assemble the delay circuit itself in the case of a non-working relay.

Scheme No. 9 (Author on Skype: polimarh16). With the start of the movement, the dipped beam turns on and the interior lighting turns off.
The illumination in the door handles turns on when the engine is running and only when the car is stationary.
There is a free contact on the relay, to which it is connected additional illumination interior (for example, illumination of door handles)

Full description of the circuit: insert the ignition key, and turn it one notch. The low beam turns on for a few seconds and goes out. We start the engine. The interior lighting (door handles and LED strip) turns on. With the start of the movement, the dipped beam is turned on, and the interior lights are turned off. After stop- reverse procedure, but with a delay of a few seconds. The delay time is provided by R3 and C2. The larger they are, the longer the duration.
The board is placed for the instrument cluster on a double adhesive tape and is connected there to the X2 connector and to the near, dimensions / far switch.

Auto headlight controllers

Who is not friends with electricians and is happy to buy a ready-made automatic headlight switch, you can use:

1. Automatic switching on of outdoor lighting (controllers LC-7-V09, LC-7-V10, LC-7-V09U)
2. DRL Headlight Control Controller (Daytime Running Lights)

According to current laws Russian Federation, in particular, amendments made to the SDA, any vehicle, carrying out movement even during the day, must be with the low beam headlights on. In addition, instead of them it is permissible to use fog counterparts, as well as daytime running lights.

In view of the fact that the operation for this purpose of the head and fog lights is associated with a number of disadvantages, the vast majority of car owners prefer to purchase navigation light modules and install them on their own. In view of this, it is worth figuring out how to connect daytime running lights with your own hands?

Operation features

Legislation quite clearly regulates the rules for the use of such elements in the design of a car. According to the requirements of GOST, the running lights should come on immediately when the ignition key is turned, and automatic shutdown should occur if the driver has activated the headlights.

In addition, such a standard provides that the inclusion of head lights should occur only after full inclusion overall analogues. The only exception is when they are used to signal. This must be taken into account when wanting to install daytime running lights with your own hands.

Do-it-yourself DRL connection, It has whole line features that need to be taken into account in order to achieve correct sequence work and long term module services. To increase its service life, it is reasonable to use a special stabilizing block designed for LED lights.

However, this measure is aimed only at increasing the duration of the circuit; without such a block, all elements will function normally.

One of the most common problems m, characteristic of DRL modules, are voltage surges, which cause overheating of the crystal responsible for the radiation. In this regard, the brightness of the lights gradually decreases, after which they cease to perform their main function.

Connection options

Considering the most common options for connecting DRLs, it is advisable to disassemble the simplest circuit connection of running lights without using a stabilizer, generator and other additional elements. In order for the DRL to be activated when the engine is turned on, it is recommended:

• Connect the positive wire to the positive terminal located on the ignition switch;
• The negative cord is fixed on the body of the car in any place convenient for the owner;
• When the ignition is turned on, the DRL will work.

The main disadvantage of such a connection scheme is the constant operation of the lights with the ignition on. Besides, the work of the lights in this case, is not coordinated with other auto lighting systems, which means that such a connection does not meet the requirements specified in GOST.

The second connection option is much more suitable for this purpose, as it uses a circuit position headlights. The positive wire of the daytime running lights, in this case, is connected directly to the battery. Negative connect with positive marker lights, after which, the LEDs begin to glow. At the same time, the lamp coil does not burn, which is associated with low current consumption.

After the parking lights are activated, the driver will be able to notice that the DRL potentials are equalized, which causes the LEDs to turn off. As a result, the car's lighting circuit switches to normal operation. Despite the fact that this scheme works without serious violations, it has a number of disadvantages so it shouldn't be installed.

It would be appropriate to include:

Since this scheme also does not meet the requirements of the state standard, it will be necessary to consider the simplest and most suitable under existing norms option.

DRL controller

For the vast majority of owners, the most acceptable is the use of a special control unit that allows you to connect the HDO via correct scheme, without the use of relays and other elements. As a result, the connection scheme is simple and safe. , due to the unique advantages controller operation.

These should include:

• Stable inclusion of DRL after starting the engine;
• Provides protection against overloads;
• Supports any type of lights, including LED;
• Does not affect the operation of other nodes.

The control units for daytime running lights, in the vast majority of cases, fully comply with the state standard, which allows them to be safely used for their intended purpose. However, some manufacturers may introduce various functions into such equipment, which, despite their usefulness, may not meet the requirements of GOST, which means that their use is not recommended.

Another advantage of this kind equipment, it is possible to connect it according to the scheme provided in advance by the manufacturer. At the same time, it must contain information about maximum load, as well as other important technical specifications. This allows you to quickly and easily connect DRL without any experience and special knowledge.

If the purchase of a special controller is not planned, it is advisable to give preference to the option of connecting through a relay. It involves the use of 5 contact relay which will be involved in general scheme DRL connections. Such a scheme allows eliminate any shortcomings inherent in the previous options and makes it possible safe use DRL without any additional equipment.

Features of connecting the DRL relay:

• 30 to "+" outputs of LED modules;
• 85 on the "+" cord dimensions;
• 86 is taken to the machine body;
• 87a on the "+" ignition;
• 87 isolate.

To implement such a connection through a relay, it is necessary to acquire wires for connection, terminals, ties, heat pipes and tools. Among other things, you should think about a way to securely fasten assembled circuit in vehicle design.

Some owners prefer use a generator in the connection diagram, which is not recommended in most cases. Indeed, in order to install DRL through the generator, you will need to install a resistor. Despite the efficiency of the scheme, its reliability leaves much to be desired.
