Rear lighting refers to the illumination systems located at the back of vehicles, primarily designed to enhance visibility and safety. These lights include tail lights, brake lights, and turn signal lights, which alert other drivers to a vehicle's presence, intentions, and actions on the road. The primary function of rear lighting is to ensure that a vehicle is seen, especially in low-light conditions or adverse weather. Properly functioning rear lights are crucial for preventing accidents, as they communicate important information to other road users, helping to maintain safe driving practices.
