Abstract: A motor vehicle headlamp assembly includes a headlamp having a light source and a reflector. A lens is bonded or otherwise fixed to the perimeter of the reflector. A surface is provided having a common radius centered on a point situated forward of the reflector which defines a segment of a first spherical surface. A fixture adapted to be mounted to a motor vehicle includes a similar spherical surface adapted to nest with the first spherical surface. The surface of the fixture and the surface of the headlamp are adjustable with respect to each other to permit alignment of light emitted from the light source to a selected direction. A fastener passes through a spherical washer and an opening in the fixture and is spherically movable within the opening over a range of positions to permit alignment of the headlamp with respect to the fixture.The first spherical surface can be provided on a rear surface of the housing or on a housing bracket coupled to the housing.
