Reverse lights are special lights on a vehicle that activate when the car is put into reverse gear. Their primary purpose is to illuminate the area behind the vehicle, helping the driver see obstacles and ensuring safety while backing up. These lights are typically white and are located at the rear of the vehicle. In addition to aiding visibility, reverse lights also serve as a warning to pedestrians and other drivers that the vehicle is moving backward. This feature is important for preventing accidents and improving overall road safety, especially in crowded or dimly lit areas.
