What mounting location is specified for high-mounted stop lamps?

High-mounted stop lamps (often referred to as third brake lights) are specified to be mounted at the top center of the vehicle as viewed from the rear. This location is chosen to maximize visibility for drivers in vehicles behind, ensuring that they can easily see when the vehicle is braking.

The top center position helps to reduce the possibility of the light being obstructed by the trunk or rear hatch, which can occur if the lamp is placed lower or on the sides of the vehicle. Moreover, this position aligns with safety regulations aimed at enhancing the visibility of braking actions in various driving conditions, contributing to overall road safety.

Other locations, such as the side mirrors or the front bumper, do not meet the requirements for high-mounted stop lamp placement, as they would not provide the necessary visibility to vehicles approaching from behind. The rear, side option would similarly fail to ensure the optimal line of sight needed for safety compliance. Thus, top center viewed from the rear is the correct specification for high-mounted stop lamps.
