ABSTRACT:
A vehicle lamp assembly, of the type in which the color of the light to be produced by the lamp cannot readily be perceived when the lamp is not illuminated, comprises a housing having an inner portion containing a light source and an outer portion enclosed by a lens arranged to collimate light from the light source. The outer portion of the housing is separated from the inner portion by a color filter. The inner surface of the side walls of the inner portion are of stepped form so as to be either substantially parallel to or substantially perpendicular to the optical axis of the assembly.
