Anyone have a good used one? My low beams suddenly quit working and I've checked the fuses. -Clark

here's one on eBay, should work on a Duetto too, I believe:

The issue is likely that your contacts are pitted, because of the high currents going through. You should install a relay to prevent this from happening. I bought a brand new switch two years ago, and hardly used it, because I hardly ever drive this car at night. So I have not installed a relay yet, and low and behold, even with this new switch my low beams stopped working. Instead of buying a new switch, you can also try what I did. I is removed it from the steering column, and drilled out the 4 rivets that hold it together. Then you can clean the contact, and bend it a little, so it'll work again. After that, I used two nuts and bolts to put it back together. The two biggest rivets I did not replace, the Allen head bolts go through these holes anyway and will pull the two halves together....I hope this makes sense, you'll probably see what I mean once you get in there. I now have a serviceable switch. Good luck

Thanks for the reply. Oddly enough, my high beams still work and since they're not terribly bright, I can use them, for now. -Clark

You can get to the contacts without disassembly. The switch has some holes in the sides where you can see the contacts. You can use a thin strip emery cloth to clean them. Open the contacts and instert the cloth. Close the contacts and pull the cloth out. Keep repeating until they are clean.

I apologize, you're probably right about that!....in my case I had to bend the lever to get them to work, requiring me to open up the switch

Thanks! I'll give it this a try. -Clark
