Abstract
Abstract A lamp lens housing made of transparent plastic material and comprising a top wall, side walls, and end walls, the top wall having portions of varying light transmitting characteristics such that a light source mounted within the housing adjacent each portion provides a different colored light emitted to a viewer. A wall of transparent plastic material extends between the side walls from the top wall and defines two chambers within the housing into which the light sources are adapted to project. The surfaces of said wall having angularly related portions defining prisms which function to reflect light striking them back outwardly so that the light from one light source will not affect the light transmitting portion of the housing adjacent the other light source.
