摘要： A vehicle headlamp assembly is provided which includes a light bulb providing a source of illumination; a reflector housing with a central opening with a reflector surface for reflecting illumination given by the light bulb, the reflector housing central opening mounting the light bulb, the reflector housing having a first surface opposite the reflector surface adjacent the central opening and a second surface on the same side of the reflector surface generally adjacent the central opening; and a bulb shield having a first portion along a first end. The first portion is generally closely adjacent to the light bulb for blocking illumination provided by the light bulb. The bulb shield has at an end opposite the first end at least one foot penetrating through the central opening with a radially outwardly extending toe engaging the reflector housing first surface. The bulb shield also has a coil spring contacting the reflector second surface urging the first end of the bulb shield away from the first and second surfaces of the reflector housing.
