Location of lighting devices on a car: diagram, standards and practical tips

Vehicle lighting is not just a design element, but a critical safety system. Not only the visibility of the road at night, but also the ability of other drivers to notice your car in time depends on their correct location. However, even experienced car owners sometimes confuse where they should be fog lightshow to distinguish side lights from daytime running lights (DRL), and why brake lights on some models they are duplicated on the rear window.

In this article we will look at unique features of the location of lighting devices on modern cars, including hybrid and electric vehicles, where the traditional scheme may differ. You will find out what the requirements are GOST R 41.48-2004 (analogous to the international standard ECE R48), how to check the correct installation of headlights after an accident or tuning, and why the placement is incorrect LED modules may result in a fine. We will pay special attention to practical advice: for example, how to independently adjust the light beam if, after replacing the lamps, it “hits the eyes” of oncoming drivers.

1. Standard layout of lighting devices: what GOST says

Valid in Russia GOST R 41.48-2004, which regulates the number, color and location of external lighting devices. This document is harmonized with the international standard ECE R48, therefore its requirements are also relevant for imported cars. Here are the key points:

• 🔦 Low/high beam headlights: must be installed in pairs, at a height of at least 500 mm and no more 1200 mm from the road level. The distance between them is at least 600 mm (for vehicles wider than 1300 mm).
• 🟡 Side lights: front - white, back - red. They can be combined with low beam headlights or installed separately (for example, in a bumper).
• 🟠 Direction indicators: front - white or amber, back - amber or red. Side repeaters (on fenders or mirrors) are required for longer vehicles 6 m.
• 🔴 Brake lights: minimum luminous area - 25 cm² for everyone. On cars after 2010 The third (upper) brake light is required.
• 🟢 Daytime running lights (DRL): Should automatically turn on when the engine starts. Their brightness is from 400 up to 1200 cd.

An interesting nuance: on cars with all-wheel drive (for example, Toyota RAV4 or Subaru Forester) installation of additional fog lights in the rear bumper - but only if they are certified and connected via a separate switch. But on electric vehicles (for example, Tesla Model 3) traditional “dimensions” are often absent: their functions are performed by LED strips integrated into the optics.

⚠️ Attention: If you install LED lamps in standard headlights designed for halogen, this can lead to incorrect light spot and blinding oncoming drivers. According to Code of Administrative Offenses 12.5 part 3There is a fine for such a violation 500 rubles.

Light fixture type	Color	Minimum height from the road (mm)	Maximum height from road (mm)	Mandatory
Low/high beam headlights	White	500	1200	Yes
Side lights (front)	White	350	1500	Yes
Fog lights (front)	White or yellow	250	800	No (but no more than 2 pcs.)
Rear fog lights	Red	250	1000	Yes (1 piece)
Third brake light	Red	850	1900	Yes (for cars after 2010)

2. Where are the low and high beam headlights located: differences by brand

On most modern cars low and high beam headlights are combined in one block, but their location may differ depending on the model. For example:

• 🚗 On VW sedans (Passat, Jetta) and Skoda (Octavia, Superb) low beam is usually implemented through lensed optics at the bottom of the headlight, and the high beam through the reflector at the top.
• 🚙 On Toyota crossovers (RAV4, Highlander) and Mazda (CX-5, CX-9) often used bi-xenon or LED modules, where switching between low and high occurs electronically, without mechanical movement of the lamp.
• 🚛 On commercial vehicles (for example, Ford Transit or GAZelle Next) the headlights can be divided: low beam - in a separate block below, high beam - in the main block above.

By car premium (for example, Mercedes-Benz S-Class or BMW 7 Series) meet adaptive headlights with dynamic light, where the location of the light spot is adjusted depending on the speed and steering angle. Such systems are often equipped matrix LED, where each diode is controlled separately.

To independently determine where the low beam or high beam lamp is located in your headlight, pay attention to:

1. Markings on the headlight housing (e.g. H7 for your neighbor, H1 for distant).
2. Reflector shape: low beams often have asymmetrical drawing to form a “tick” of the light spot.
3. Availability flaps (for halogen headlights) or lenses (for xenon/LED).

3. Side lights and daytime running lights (DRL): what's the difference and where are they installed?

Many drivers are confused side lights and daytime running lights (DRL), although their functions and location are fundamentally different:

• 🔆 Side lights (position lamps): used to indicate the dimensions of the car at night. In front they white, behind - red. On most vehicles they are built into the headlight or taillight assembly, but on some models (e.g. Lada Granta or Kia Rio) can be placed in the bumper.
• ☀️ Daytime running lights (DRL): designed to improve vehicle visibility during the day. They brighter than dimensions (from 400 cd) and turn on automatically when the engine starts. Most often located:
• At the bottom of the headlight (for example, Audi A4, Volvo XC60).
• In the bumper in the form of an LED strip (for example, Hyundai Tucson, Kia Sportage).
• In a separate module on the eyelashes of the headlight (for example, BMW 3 Series).

Important point: according to Traffic regulations (clause 19.5), during daylight hours you can use DRL instead low beam headlights or fog lights. However, the latter is permitted only if they steam room installation from the front. In practice, the use PTF instead of DRL leads to rapid lamp burnout due to constant load.

On electric vehicles (for example, Tesla Model Y or Nissan Leaf) DRLs are often integrated into a single LED module with turn signals and markers. Such solutions save energy and improve design, but complicate self-repair: if one diode fails, the entire unit may need to be replaced.

What happens if you drive without DRL?

According to Code of Administrative Offenses 12.20 Part 1, the absence of daytime running lights (or their equivalents) will result in a warning or fine 500 rubles. However, in practice, inspectors rarely stop you for this violation if you have your low beams on. The exception is cars with tinted headlights, where the visibility of lamps is impaired.

4. Fog lights (FTL): where to look for them and how to use them correctly

Fog lights - one of the most controversial elements of automotive lighting. Their location is strictly regulated:

• 🟡 Front: no more 2 pieces, at an altitude of no less 250 mm and no more 800 mm from the road. They should be no further 400 mm from the side surface of the car (along the outer edge).
• 🔴Rear: only 1 lantern (required on the left side), at height 250–1000 mm.

On most cars, the front PTFs are located:

• In the bumper (for example, Volkswagen Golf, Ford Focus).
• In the radiator grille (for example, Toyota Camry, Mitsubishi Outlander).
• In a separate module under the headlight (for example, Renault Logan, Dacia Sandero).

However there are exceptions:

• On SUVs (for example, Land Rover Defender or Jeep Wrangler) PTF can be installed on the roof or on the bumper as additional led bars.
• On commercial vehicles (for example, Mercedes-Benz Sprinter) the rear fog light is sometimes duplicated on both sides.

⚠️ Attention: Using front PTF instead of daytime running lights prohibited in urban conditions (clause 19.4 of traffic regulations). They can only be enabled under conditions fog, rain or snowwhen visibility is less 300 meters. Violation is punishable by a fine 500 rubles.

When installing additional PTFs (for example, on a bumper or roof), remember:

1. They must be certified (be marked E or EAC).
2. The angle of illumination should not exceed ±5° vertically and ±45° horizontally.
3. The connection must go through relay, and not directly to the on-board network.

5. Brake and Tail Lights: Why a Third Brake Light is Mandatory

Rear lights are not only brake lights, but also dimensions, turn signals, reversing light and fog light. Their location is standardized, but there are nuances:

• 🔴 Brake lights: must be red and turn on when you press the brake pedal. Minimum luminous area - 25 cm² for everyone. On cars after 2010 required third brake light (usually on the rear window or spoiler).
• 🟡 Turn signals: the rear ones should be amber or red (but not white!). On some vehicles (for example, Audi A6) they are integrated into the main block of the flashlight in the form of a dynamic strip.
• 🟢 Reversing light: required white. On crossovers (for example, Nissan Qashqai) it is often combined with a fog lamp.
• 🔴 Rear fog light: only 1 piece (left), red. On some models (for example, Volvo XC90) it can be duplicated on the right, but this does not correspond to GOST.

Third brake light (aka CHMSL — Center High Mounted Stop Lamp) appeared without fail after 2010. Its task is to reduce the reaction time of the rear driver to braking. According to research NHTSA (USA), its presence reduces the number of rear collisions by 17%. On most cars it is located:

• On the inside of the rear window (for example, Toyota Corolla, Hyundai Solaris).
• On the spoiler (for example, Subaru Impreza, Mitsubishi Lancer).
• At the top of the rear door (for example, Ford Transit, Peugeot Boxer).

If the third brake light does not work, it is considered malfunction, in which operation of the vehicle is prohibited (clause 3.6 List of faults). In practice, inspectors rarely check its work, but when passing technical inspection this may cause failure.

6. Features of the location of lighting devices on electric vehicles and hybrids

Cars with electric and hybrid power plants often have unique lighting solutions. This is due to:

• 🔋 No engine noise (therefore it is important that the car is clearly visible).
• 💡 Using LED and OLED- technologies for energy saving.
• 🎨 Integration of lighting into the overall design (for example, light strips).

Examples of unique solutions:

• 🚗 Tesla Model 3/Model Y: There are no traditional “dimensions” - they are replaced by LED strips in the headlight. The daytime running lights are integrated into the lower part of the headlight and are a continuous line.
• 🚗 Audi e-tron: uses matrix LED headlights with dynamic turn signals. The taillights are a solid LED panel with animation.
• 🚗 BMW i4: front optics have hexagonal structure, where each element is controlled separately. The taillights are designed as a thin LED strip.
• 🚗 Hyundai Ioniq 5: “pixel” headlights with the ability to project symbols onto the road (for example, arrows when turning).

Also often found on electric vehicles:

• Active lighting: The headlights automatically adjust the brightness and direction of the light depending on the driving conditions.
• Projection headlights: Can display speed limits, lanes, or even pedestrian crossings on the asphalt.
• Color accents: for example, blue or blue backlights (allowed only if they do not dazzle and are not confused with brake signals).

Important nuance: on electric vehicles no generator, so all lighting devices are powered by a high-voltage battery. This means that:

• 🔋 LED lamps consume less energy than halogen ones, which increases the power reserve.
• ⚡ When the battery is low 20% Some manufacturers automatically turn off DRL or dim headlights.
• 🔧 Replacing lamps or headlight units on electric vehicles often requires special equipment (for example, to reset errors in the control unit).

7. How to check and adjust lighting devices yourself

Even if the lights are positioned correctly, their incorrect adjustment can result in a fine or an accident. Here's how to check and adjust the lighting yourself:

Functionality check:

1. Turn on dimensions and walk around the car - all lamps should light evenly, without blinking.
2. Have an assistant press the brake pedal - check all brake lights, including the third one.
3. Turn on low beam and look at the asphalt in front of the car: the light spot should be asymmetrical (the right side is higher than the left for right-hand drive countries).
4. Check fog lights — their light should be scattered in a wide beam low above the road.

Headlight adjustment:

1. Place the car on a level surface 5 meters from a wall (for example, a garage).
2. Place marks on the wall corresponding to the centers of the headlights (the distance between them should match the distance on the car).
3. Mark a horizontal line on 5–7 cm below center of the headlights (this is the level of the light spot for the low beam).
4. Using the adjusting screws on the headlight (usually located on the top and side), ensure that the top edge of the light spot coincides with the horizontal line.

Different types of headlights have their own nuances:

• 🔦 Halogen headlights: adjustable mechanically with screws on the housing.
• 💡 Xenon headlights: often have autocorrector, which is configured via the on-board computer (for example, Menu → Settings → Lighting → Headlight range control).
• 🟡 LED headlights: may require flashing the control unit after replacing lamps.

⚠️ Attention: If, after adjusting the headlights, they still dazzle oncoming drivers, the problem may be wrong lamps (for example, installed LED instead of halogen) or in damaged reflector (often found after an accident).

8. Frequent errors and fines: what inspectors check

Violations in the location or operation of lighting devices are one of the most common causes of fines. Here's what inspectors check most often:

Violation	Fine (CAO)	Can it be fixed on site?
One side light is missing	500 rub. (Part 1 Article 12.20)	Yes (if there is a spare lamp)
Brake lights don't light up	500 rub. (Part 1 Article 12.20)	Yes (if the problem is the lamp or fuse)
Installed LED lamps in halogen headlights	500 rub. (Part 3, Article 12.5)	No (certification required)
Fog lights are turned on unnecessarily in the city	500 rub. (Part 1 Article 12.20)	Yes (enough to turn off)
Tinting headlights or taillights	500 rub. (Part 3, Article 12.5)	No (requires film removal)

The most common mistakes made by car owners:

• 🔧 Installation non-certified LED lamps into standard headlights. Even if they “shine well”, their use prohibited, if the headlight is not designed for LED.
• 🎨 Tinting headlights or taillights film or varnish. This reduces light transmission and can cause an accident.
• 🔌 Connection of additional headlights (for example, on the roof) without relay and fuse. This may cause a fire.
• 🔄 Replacing lamps without checking polarity (relevant for LED). Incorrect connection leads to flickering or failure of the control unit.

If you are stopped by an inspector for faulty lights, you can:

1. Correct the fault on site (for example, replace the lamp).
2. Provide documents confirming that the headlights certified (for example, for LED lamps).
3. If the fine has already been issued, pay it at a discount 50% within 20 days.

FAQ: Frequently asked questions about the location of lighting fixtures

Is it possible to install additional brake lights on the rear window?

Yes, but only if they certified and do not interfere with the view. According to GOST, installation is allowed only one additional brake light (in addition to the two main ones and the third one on the glass). It should be red and turn on simultaneously with the main brake lights. In practice, such lights are often installed on SUVs or commercial transport for better visibility.

How are daytime running lights (DRLs) different from parking lights?

Main differences:

• Brightness: DRL should shine with an intensity of at least 400 cd, and dimensions - from 4 cd.
• Automation: DRL turns on automatically when the engine starts, dimensions - only when you turn the switch.
• Purpose: DRLs improve visibility of the car during the day, dimensions indicate its dimensions in the dark.

On some vehicles (for example, Volkswagen Polo) DRLs are implemented via dimming low beam, which is not entirely correct from the point of view of GOST, but is allowed by the manufacturer.

Is it possible to drive with one working low beam headlight?

No. According to Traffic regulations (clause 19.1) and List of faults (p.
