I use to have a pair of driving lights mounted on my front fender. Same story as Rob, I lost one of the rings one day. I pulled the lights off the next day and ordered another set. I just havent mounted them again, just not sure yet how I want to mount them next time. They are the Optronics qh-7cc lights as well. For $20 (including shipping) you cant complain much at all.
