nice KACO accessory light with K plug

Vintage Kaco accessory light with original “k” marked power plug in good condition. The light, cable and plug are all original and in good condition. The cool “K marked” plug fits in 2 cm diameter power sockets. I tested the light with 12V and it is working very well but I guess the bulb is for 6V because it was very bright. I can check and change the bulb, just let me know what you like. It can be used for 6/12 volt and was made in Germany. A classic accessory for VW Beetle, Bus, Karmann Ghia, Type 3 and Porsche.
