Hi Steve, I did the repair on the switch shown on the Experience Forum. It's not in a car but I've cycled it about 100 times and it seems OK. The metal contact affair the ball rolls over is pretty touchy and hard to fix if it gets bent or out of alignment. Take the halves apart carefully by drilling out the glue in the 6 depressions and carefully separating. Watch out for the spring and steel BB that are probably loose in the bottom. I put the headlights on a relay so the 8 or so amps wouldn't have to pass through the switch. Jeff
