A Tail Light of unknown manufacture, but possibly American as it was fitted to a car registered in Australia.
Diameter is about 3.75" (95mm). It has a very nice one-piece red glass lens and it is fitted with a double-contact bulb holder, with all parts demountable and of nice quality (originally!).
It has unfortunately been 'modified' at some po..
Original new-old-stock German Bosch combined stop-tail-number plate lamp.It is in excellent condition, still with its box. It has a metal body with a plastic lens.I can send more photos on request, and I accept PayPal.
