ABSTRACT:
An instrument panel member comprising a multiple-ply back sheet of fiberglas reinforced material impregnated with a polyester resin, a multiple-ply front sheet of the same material and one or more electroluminescent (EL) lamp elements positioned therebetween. The overall structure is cured at a temperature and pressure selected to provide adequate curing without damage to the EL lamp elements and so as to minimize warpage of the final structure. The thickness of the back sheet is selected to accommodate the dimensions of the EL lamps and any electrical connectors used therewith while the thickness of the front sheet is normally much less and need only be such as to permit light from the EL lamps to be seen therethrough.
