  • Patent number: 6068392
    Abstract: A motor vehicle headlight is disclosed which has a lamp body having a open front end closed by a lens to define a lighting chamber, and a light source with a reflector mounted in the lighting chamber. Also disposed in the lighting chamber is a reflector extension of approximately tubular shape interposed between the reflector and the lens for concealing the gaps between the reflector and the lamp body. The reflector extension has a mounting fin extending upwardly therefrom which is frictionally engaged between the lamp body and the lens, thereby dispensing with fasteners. Extending downwardly from the reflector extension, another mounting fin may be screwed to either the lens or the lamp body because the screws under the reflector extension are hardly visible from outside the headlight in its use on a motor vehicle.
