For most Ukrainian drivers, from October 1 to May 1, a reflex kicks in: "Turn on the lights!" This is a direct requirement of the Traffic Rules (PDR), designed to increase safety during shorter daylight hours. However, the need to constantly use low-beam headlights not only increases fuel consumption (albeit minimally) but also significantly reduces the lifespan of the bulbs, especially on older cars.

The solution to this problem is Daytime Running Lights (DRL). According to the PDR, DRLs are external light devices designed to improve the visibility of a vehicle while driving during daylight hours. Their function is purely signaling, not illuminating.

If your car is not equipped with factory DRLs, you have every right to install them yourself. However, this must be done in strict compliance with European and national standards to avoid unpleasant situations with the police and avoid a "daytime running lights fine." Let's figure out how to do it legally.

Why DRL is a Necessity, Not a Luxury

The main advantage of daytime running lights is safety. According to studies, using these lights reduces the risk of collisions by 5–15% during daylight hours, as the vehicle becomes more visible from a distance, especially against a background of trees or asphalt.

Daytime running lights have two other important advantages over low-beam headlights:

Energy Efficiency: High-quality LED DRL modules consume 5–10 times less energy than standard low-beam bulbs (halogen or xenon). This, accordingly, reduces the load on the alternator.

Resource Preservation: Constant use of low beams, especially in city driving (with frequent stops and engine starts), shortens the bulbs' lifespan. DRLs are specifically designed for continuous operation.

The Legal Side: What Do the Ukrainian Traffic Rules (PDR) Say?

Ukrainian Traffic Rules clearly regulate when and what must be turned on. Let's look at the key point concerning our topic:

Clause 9.8 of the PDR of Ukraine: From October 1 to May 1, all mechanical vehicles outside populated areas must have daytime running lights turned on, and in their absence in the vehicle's design — low-beam headlights.

Thus, between October and May, for driving outside cities, you have a choice: DRLs or low beams. If you use legally installed running lights, you fully comply with the PDR and avoid fines.

How to Legally Install DRL: Key Certification Requirements

The biggest mistake drivers make is installing non-certified or incorrectly positioned lights that visually resemble DRLs. A police inspector looks not at the presence of light, but at its compliance with technical regulations.

For your self-installation to be legal, it must comply with European standards ECE R48 (Installation of lighting and light-signaling devices) and ECE R87 (Requirements for the DRLs themselves).

Design Requirements (ECE R87)

When choosing which daytime running lights to buy, pay attention to the markings:

Certification Presence: The lens must have the "RL" (Running Light) marking and an official approval mark "E" in a circle with the country code that issued the certificate (e.g., E4 – Netherlands).

Light Intensity: The light must be white and have an intensity within a specific range (not too bright to blind at night, and not too dim).

Placement Requirements (ECE R48)

Correct placement is 90% of a successful legalization. Deviating from these parameters is grounds for a fine, as it is considered a modification in violation of standards.

Note: If your vehicle's width is less than 1.3 meters, the minimum distance between DRLs can be reduced to 400 mm.

Step-by-Step Instructions for Selection and Installation (Fine-Free)

1. Correct Equipment Selection

Avoid the cheapest LED strips or unmarked modules. Your running lights must have clear RL and ECE markings. It is better to pay more for a certified product than to spend on fines later.

2. Precise Placement Planning

Before drilling or mounting, ensure that the location you've chosen meets all the parameters in the ECE R48 table. Most often, drivers use spots in the bumper grille or special niches at the edges of the bumper.

Important: Light devices must be placed only at the front and must be visible. They must not be obstructed by the bumper, bull bars, or other equipment (e.g., a winch).

3. Wiring Diagram (Automation is Mandatory)

The most important requirement for DRL operation is its automation. They must:

Turn on automatically when the engine starts.

Turn off automatically or switch to parking light mode when the low-beam headlights (or fog lights) are turned on.

For this, you need to use a special control unit that usually comes with high-quality modules. A simple DRL wiring diagram involves connecting power to the ignition (via a relay) and a trigger wire to the low-beam circuit.

4. Main Installation Steps

1. Identify and mark the mounting points according to ECE R48 requirements.
2. Securely mount the modules in the bumper using the manufacturer-provided brackets.
3. Connect the DRL control unit to the electrical system, ensuring it is powered by the ignition circuit.
4. Connect the trigger wire to the low-beam (or parking light) circuit so the DRLs automatically turn off when they are switched on.
5. Test the system: The lights should only be on when the engine is running and the low beams are off.

Equip Your SUV with Legal Lighting

Installing DRLs legally is not as difficult as it seems if you follow two key rules: use certified modules (RL, E marking) and strictly adhere to the placement parameters specified in European regulations. Compliance with these simple requirements will allow you to avoid fines during the mandatory lighting period and, more importantly, significantly save the resource of your main headlights.
