Reverse lights are a type of vehicle lighting that activates when a car is put into reverse gear. Their primary purpose is to illuminate the area behind the vehicle, helping drivers see obstacles and pedestrians while backing up. These lights are typically white and are located at the rear of the vehicle. In addition to providing visibility, reverse lights also serve as a safety feature. They signal to other drivers and pedestrians that the vehicle is moving in reverse, reducing the risk of accidents. Most modern vehicles are equipped with these lights as part of their standard lighting system.
