ABSTRACT:
The vehicle lamp assembly comprises a housing having a window therein. Disposed within the housing is a first ellipsoidal reflector, a mask, a second ellipsoidal reflector, and a concave mirror. The mask is disposed in the inner focal planes of the respective reflectors and is also disposed at the focal plane of the concave mirror. The second reflector is disposed on the opposite side of the mask to the first reflector and the mask on the side thereof facing the second reflector is silvered. When a filament in the first reflector only is illuminated, a dipped beam pattern is provided. When both of the filaments are illuminated, a full beam pattern is provided because the dipped beam pattern is modified by light from the second reflector being reflected off the mask towards the concave mirror.
