DRL stands for Daytime Running Lights, which are low-voltage white lights on the front of cars that operate when the headlights are not engaged. They are also called daytime running lamps. DRLs are found on the front fascia near the sides of the vehicle and are automatically activated when the vehicles ignition is engaged. They are meant to enhance road safety by helping drivers see other vehicles quickly during the day when most drivers turn their headlights off. DRLs are not meant to substitute headlights and are not fog lamps.
DRLs are required on all new vehicles made or imported after January 1, 1990, in Canada. In the US, despite the governments lack of action, most new passenger cars, SUVs, and light trucks sold have DRLs. Some insurance companies may provide discounts to drivers with vehicles using DRLs.
If the DRL warning light is on, it usually means there is an issue with the vehicles daytime running lamps or other vital components of the cars safety system. Common causes for a DRL warning light to illuminate include a short circuit in the wiring for the daytime running lamps, a blown fuse, or a defective DRL relay. It is important to diagnose and repair the issue as soon as possible to avoid any further damage to the car.
