Abstract
An improved remote headlamp system includes a single light source operable in conjunction with a reflector arrangement constructed in a manner so as to generate at least two light spots from such single light source. These two light spots are picked up by the separate input ends of light transmissive elements such as optical fibers or light guides. The output ends of the light transmissive devices are directed to either side of the automobile with one side being imaged by a lens or mirror element to provide the spread portion of the standard pattern of road illumination and the other side being imaged by another lens or mirror element to provide the narrow, focused portion of the road illumination pattern. An arrangement for switching between high and low beam operation is also provided.
