Novel blinker lamp – Black vision

As a styling feature a blinker lamp is proposed which is black in the off-state and amber in the on-state. The lamp can be produced by applying a black layer to an already amber/yellow blinker lamp. Such a substrate can easily be produced by using colored glass or by applying a colored coating e.g. as a sol-gel coating used for for example Silver Vision lamps. The black layer can e.g. be produced by depositing a black metallic layer in a sputter deposition process onto the colored lamp. Typical materials employable are Si, Zr, Nb, Ta, Ti, Al, Hf, Fe etc. If necessary the metallic layer can be protected by a transparent oxide layer produced in the same sputter deposition process. Typical materials are Silica, Hafnia, Alumina, Zirconia, Tantala, Niobia and Titania. The principle can be easily expanded to other deposition processes. The principle can be expanded easily to other colors, too, e.g. red color for stop lamps.
