Abstract: A motor vehicle rear light assembly designed to be used in addition to the conventional vehicle brake lights includes a housing adapted to be mounted at the rear of a vehicle and having at least three compartments each containing a light source such as one or more light bulbs. The light sources are operated by a suitable control circuit, which may be connected to the vehicle brake lighting system, so that the central light source is switched on to burn continuously as long as the brakes are applied and the outer two light sources flash alternately on and off a predetermined number of times as soon as the brakes are applied and then burn continuously until the brakes are released. Mounting brackets which are rotatably mounted on the housing are used to mount the housing on a vehicle in the desired orientation.
