Daytime Running Lights (DRL)
Daytime running lights are lights at the front that switch on automatically during the day to make the car more visible.
What is Daytime Running Lights (DRL)?
They are mandatory on new cars in the EU and many other regions. They are usually LED strips; some cars use dimmed low beams. They do not light the road and do not switch on the rear lights on many cars.
How it works
They switch on with the engine and often dim or turn off when the headlights or indicators are on.
Why it matters for your car
Relying on DRL at dusk can leave the rear of the car unlit; switch on the headlights. A failed DRL may be an inspection defect.
