A DRL light, also known as Daytime Running Light, is an automotive lighting feature designed to enhance the visibility of a vehicle during daylight hours. DRL lights are typically located at the front of the vehicle and are bright enough to be seen clearly in daylight conditions, but not so bright as to cause dazzle. These lights automatically turn on when the engine is started and turn off when the headlights are switched on. The purpose of DRL lights is to increase the visibility of the vehicle to other road users, reducing the risk of accidents. They are not intended to illuminate the road or serve as rear marker lights. Instead, DRL lights are specifically designed to make the vehicle more visible to other drivers, especially in low light conditions.
