German car lamp with plug

Vintage German car lamp with plug in good condition. The total length is 17 cm and the diameter is 8 cm. I tested it and it is not working. Possible the bulb is not ok. There is a metal clip around the lens (see last pic) and with that you can remove the glass lens and replace the bulb. I did not try because it takes too much time. I can replace the bulb with a 6V or 12V bulb and put a spare extra bulb in your box for +30 USD, just let me know before you buy. Made in Germany.
