Abstract
A lamp assembly is disclosed as adapted for use as a supplemental high mounted stop lamp for motor vehicles. A lamp body has a paraboloidal reflector for producing parallel rays of light from a source mounted therein. For reducing the axial dimension of the lamp body to a minimum, a generally planar lens is mounted at its open front end, with the lens having a multiplicity of prism elements formed on its outer surface for internally reflecting the parallel rays in a direction at a considerable angle to the axis of the reflector. Additional embodiments are disclosed for imparting both lateral and vertical divergence to the light beam emitted, and for producing two vertically overlapping light beams.
