DRL – Daytime Running Lights

Daytime running lights are lights mounted at the front of a vehicle for the purpose of ensuring that the car is visible to other road users – especially during the day.

Daytime running lights are automatically switched on when the car is put into drive mode during daylight hours when the headlights are not switched on.

On some cars the daytime running lights are deactivated when the headlights are switched on.

Daytime running lights significantly increase the ability for other drivers, cyclists and pedestrians to be able to see a car – especially in low light situations such as dawn, dusk, or fog.

This increased visibility makes them an important safety feature – so much so that some regions now require all new cars to be fitted with them.

Manufacturers are also increasingly using daytime running lights as a stylistic element of the car design and using them to reinforce their brand identity.
