Surprisingly, that's the only part that I haven't had off of the Spyder. I undid the four bolts and all the panels. What I didn't know was why the light would only move out about 2 inches. Never even thought about the adjustment nut having to be undone. You just saved me from doing some serious damage to the bike. It took over 30,000 miles before I lost a light. Replacing both while I'm in there!
