Abstract: Flexible elongated light conductor comprises elongated transparent plastic member which carries a protective overcoat of shrink-fitted light-transmitting material. The light conductor can be conformed into letters or indicia and when end lighted, generally resembles a neon sign. The snugly fitting overcoat improves the light-emitting performance of the light conductor and enables the conductor to be bent through relatively small radii turns to form letters, etc. without distorting the overcoat, which distortions if present, would introduce objectionable variations in appearance.
