High-Mounted Stop Lamp (HMSL): Global Market, Suppliers, and Procurement Guide

1. Introduction to the High-Mounted Stop Lamp

The High-Mounted Stop Lamp (HMSL), also known as the center high-mounted stop lamp (CHMSL) or third brake light, is a mandatory safety device installed at the center of a vehicle’s rear, typically at the top of the trunk lid, rear window, or tailgate. Its primary function is to provide a clear and elevated signal to following drivers when the vehicle is braking, significantly reducing the risk of rear-end collisions. Introduced as a regulatory requirement in the United States in 1986 and subsequently adopted globally, the HMSL has evolved from a simple incandescent bulb unit to advanced LED arrays, integrating with vehicle lighting systems and contributing to overall automotive safety standards.
