The tail lamp, also referred to as the tail light, is a vital safety component situated at the rear of a vehicle. It comprises a red light that activates when the headlights are in use, serving as a visual signal to other motorists and pedestrians. This feature enhances the vehicle’s visibility in low-light conditions and adverse weather, thereby mitigating the risk of rear-end collisions. Additionally, it incorporates brake lights and turn signal indicators to communicate the driver’s intentions to surrounding traffic. Ensuring the proper functionality of the tail lamp is imperative for upholding road safety and adherence to traffic regulations.
