Abstract
A vehicle lamp assembly comprising a reflector, with three (3) mounting bosses arranged in a triangular fashion on the rear side thereof, a light source and a housing. Three (3) pivot sockets are fixedly attached to each mounting boss, respectively. The vehicle lamp assembly also comprises two (2) ball pivot adjusting screws that are movably secured within two (2) of the three (3) pivot sockets, and an actuator ball pivot that is movably secured within the third pivot socket. An actuator is fixedly attached at one end to the housing and attached at the other end to the actuator ball pivot in a manner that permits linear motion of the actuator. The invention further comprises a vertical adjuster plate and a reflector plate. Movement of the actuator causes the reflector to adjust in both the horizontal and vertical directions, thus allowing the vehicle lamp assembly to produce both low beam and high beam lighting functionality.
