ABSTRACT:
A periscopic lens in a lamp assembly in which parallel light rays are twice reflected and pass through optical surfaces which control the light distribution pattern beyond the lamp assembly. The light rays enter the lens and emerge only from alternate lens facet surfaces, with the surfaces or facets alternating therebetween being so arranged as to present the same color as that of adjoining vehicle body panels to visually merge the lamp assembly with the coloration of the body panels and present a continuous appearance while the lamp assembly is not energized. At the same time it permits the lamp assembly to be seen as needed when it is energized. Optical surfaces are provided which establish a desired light distribution pattern which may be other than diffusion beyond a light ray focal point.
