Abstract

A license plate system for motorcycle, car, truck or boat including a row of lights supported along an edge of a clear plastic channel so that light from the row enters the interior of the pane through an edge surface of the panel. The front surface of the panel has an area that is textured to form the alpha-numeric characters of the license. The panel is sufficiently thin ( 1/8 to ½ inches) so that Light from the row of lights is confined between the front and rear surfaces of the panel except an area of the front surface that is textured. Therefore the contrast between the illumination of the textured area compared to the smooth area is very pronounced.
