ABSTRACT OF THE DISCLOSURE A rectangular housing having an open front face bordered by track grooves which slidably receive a plurality of self- diffusing, and laterally interlocked panels. A source of illumination mounted inside of the housing is controlled by a photoelectric cell exposed to ambient light through one of the panels abutting a removable end wall of the housing. An internal arcuate reflector directs illumination from the source onto the panels and a light transmissive bottom wall of the housing while reflective coatings on the end walls prevent illumination fade out at the end panels. Also, a one-piece transparent housing of an information display device, has a supporting lens wall on which a display panel is held by a frame. A source of illumination mounted inside of the housing is controlled by a photoelectric cell projecting into a bubble formation on the supporting wall of the housing, exposed to the ambient light through aligned openings in the display panel and the frame in the plane of the indicia bearing surface of the display panel. Illumination from the source reflected from a back panel secured to the housing, illuminates the display panel and is transmitted by portions of the housing projecting through window openings in the frame.
