Abstract
Abstract A combination lamp assembly suitable to be mounted to the rear of a motor vehicle, comprising a lamp housing defining two or more lighting compartments each having at least one light source mounted therein. In one embodiment the front ends of two lighting compartments are closed by respective inner lenses and further by two sections of a common outer lens. One of the outer lens sections is transparent and colored in red. The other outer lens section has alternating transparent stripes and opaque stripes. The transparent stripes are colorless whereas the opaque stripes are colored in red. When the light sources are unlit, the outer lens appears wholly red, due in part to the illusory effect of the opaque red stripes. However, when lit up, the two lamp units project red and white light through the transparent red section of the outer lens and through the colorless transparent stripes of the other outer lens section, respectively. Changes in color and in the arrangement and configurations of the lamp units are possible to provide various combinations of a tail and stop lamp, a backup lamp, a turn signal lamp, etc.
