Abstract
A lighting system particularly suited for aerodynamically styled automobiles and aircraft is disclosed. The lighting system emits light from a strip arranged across a vehicle such as the automobile. The lighting system may comprise various subsystems finding application for the high and low beam frontal illumination and rear illumination all of the automobile. Each of the subsystems comprises a high intensity light source coupled to one end of each of a plurality of light pipes or optical fibers with each having their other end preferably positioned relative to a reflective element and lens. The reflective elements are arranged relative to a lens element to provide a prescribed illumination patterns. In one embodiment the lenses are arranged relative to each other and are located across a strip of the automobile to provide a composite beam to serve the needs of the high and low beam illumination patterns for the automobile.
