Up for sale is a good used, functional VW/Audi headlight switch. These are reasonable easy to exchange. Pop it out, and plug in the new one. Check your original part number for fitment details.  I have tested this unit for correct resistance with an ohm meter and it works properly through it's working range. It will come to you as seen. These are starting to be VERY hard to find in good working condition, Bargain alert!!! Keep your classic VW / Audi going.
