Abstract
A lamp includes a bowl shaped reflector having an elongated aperture in its base for mounting a light source. A light source including a filament enclosed in a transparent envelope is mounted in the aperture such that when the light source is illuminated light is projected from the front of the reflector and also escapes through the aperture to the rear of the reflector. A lamp housing extending behind the reflector is transparent and includes a color filter material. Light projected from the front of the reflector provides light for illumination, while light escaping through the aperture in the reflector is transmitted through the color filter material and provides a safety signal.
