The paper deals with the current progress in rear lighting technology. In developing the best vehicle in terms of traffic and driver safety, a rear signal light becomes increasingly important. Many car manufacturers are offering an LED CHMSL (Center High Mounted Stop Lamp) as one mean of increasing traffic safety. This investigation is based on the comparison of reaction times between lighting devices equipped with conventional incandescent bulbs and those equipped with LEDs. In combination with the CHMSLs, LED signal lamps provide value in styling and safety features. Laboratory measurements had already been done resulting in shorter reaction times with LEDs. This study discusses experimental analysis of driver reaction times in response to the stop function of rear lamps including CHMSLs.
