A backlit display apparatus mounts to an exterior surface, including an automobile, wherein plain paper designs, digital photographs on plain paper or transparencies may be displayed between a white translucent dispersing panel and a clear front panel, with the front panel and the dispersing panel having a weather-proof seal. A high lumen light source, which could consist of a single bulb or a plurality of low lumen light sources, is located behind the dispersing panel, powered by either an internal DC electrical power source, an external DC electrical power source or an external 110 volt AC power source, the high lumen light source having a variable illumination control mechanism to select from a constant illumination, a flashing illumination or a passive illumination, such passive illumination derived from the external power source, including the brake light electrical system or the running light electrical system of an automobile to which the apparatus may be attached.

1. An exterior back-lighted display device for display of transparent or plain white paper printed medium on an exterior surface, the device comprising: a. a base frame having a back portion, side portions and a front perimeter rim defining an inner cavity, the inner cavity containing a concave reflective insert in front of which is oriented a high lumen light source; b. a white translucent display panel positioned within the inner cavity in front of the high lumen light source, providing a back-lighted surface upon which the transparent or plain white paper printed medium is displayed; c. a means of selection of a lighting sequence located within the inner cavity, allowing for selection of a constant on, an off, a sequential flashing and a passive mode, the means of selection of a lighting sequence further placed behind the reflective insert, partially projecting through at least one side portion; d. a means of selection of a power source located within the inner cavity allowing for selection of a 110 volt external power source, an external DC power source, and an internal DC power source supplied by an internal power supply, the means of selection of a power source further placed behind the reflective insert, partially projecting through at least one side portion; e. an electrical socket located within the inner cavity, behind the reflective insert, partially projecting through at least one side portion, the electrical socket connected to the high lumen light source through the means of selection of a lighting sequence and the means of selection of a power source; f. a first electronic connection connecting the electrical socket and an external DC power source; g. a second electronic connection connecting the electrical socket and an external AC power source, the second electronic connection having a transformer converting 110 volt AC current to DC electricity, the transformer plugging into a standard two-prong AC electrical outlet; h. a hinged front frame connected to the base frame by at least two hinges, the hinged front frame having an inner surface and an outer surface, the inner surface having a perimeter edge having a weather-proof seal engaging the front perimeter rim of the base frame when the hinged front frame is closed against the base frame, wherein a weather resistant transparent front cover is attached to the inner surface of the hinged front frame; and i. a means of removable attachment to an exterior surface, attaching the rear surface of the base frame to the exterior surface. 2. The device as disclosed in claim 1, further comprising: the first electrical connection has an electrical plug on a first end which engages the electrical socket of the device and a second end having two wires for integrated connection to an electrical wiring system in an automobile and a 4-pin socket connecting to a standard trailer electrical socket on an automobile, the first electronic connection providing electrical attachment to the automobile 12-volt DC electrical system. 3. The device as disclosed in claim 1 wherein a keyed lock is incorporated into the hinged frame to secure the hinged front frame to the base frame.
