Although the High Beam and Daytime Running Light (DRL) operate on the same bulb, the High Beam/DRL light bulbs are separate from the headlights (low beams). This condition does not impact the ability to continue to use regular (low beam) headlights in the event a High Beam/DRL bulb were to become inoperative. Page 1 of 5
