Abstract
A decorative panel assembly for vehicles, appliances or other applications including illuminated indicia, isignia or designs in registry with at least one transparent area in one of two panels. Illumination of the insignia/designs is made with a thin, composite electroluminescent lighting assembly which substantially avoids lamination problems between the supporting panels. Electrical connections are made through at least one transparent, electrically conductive coating on at least one of the panels such that the illuminated insignia, indicia or designs appear to "float" within the panel assembly without any electrical connections being visible around the illuminated element.
