Abstract
A lamp assembly with a solid, opaque panel perforated by at least one aperture producing a silhouetted symbol representative of a traffic or pedestrian message and a reflective coating affixed to the light-facing inner side of the panel that reflects light. The lamp assembly further includes at least one optical element that scatters the reflected light through the mask at a plurality of angles relative to the path of the emitted light passing directly from the light source and a low reflective, dark colored layer affixed to the outer side of the mask in order to provide contrast with the light passing through the pattern of apertures.
