Daytime Running Lamp: Description and Operation



- Daytime Running Lamps - Daytime Running Lamps (DRL) are standard equipment on vehicles manufactured for sale in Canada and optional on vehicles manufactured for the United States. Vehicles with DRL enabled illuminate the high beam filament of each headlamp bulb (except Patriot with Trail-Rated option for the United States market, which uses the low beam filament) at a reduced intensity to serve as the DRL.
