ABSTRACT:
An illuminated vehicle display apparatus has a flexible electroluminescent panel having a front planar surface which directly generates illumination when excited by an alternating current. A thin flat flexible opaque shield has cutout areas to form designs therein and is attached over the electroluminescent panel planar surface so that portions of the panel are visible through the opaque shield so that indicia and graphic designs are defined by the visible electroluminescent light. A thin flexible magnetic sheet of material is attached over the rear surface of the electroluminescent panel for removably attaching the vehicle sign to the side of a vehicle. The electroluminescent panel has a pair of conductors coupled thereto and through a DC to AC converter and is attached to the vehicle battery, such as through the vehicle cigarette lighter. A pair of panels may be attached to both sides of the vehicle on the doors adjacent the door hinge so that the conductors pass through the hinged area and are attached to a common cigarette lighter plug for powering panels on each side of the vehicle simultaneously.
