I have had them for almost 3 years, I like them they clean up the back of the bike nice but the quality of the lense is dicey. I used to work maintenance at a injection moulding plant making the same parts for cars so I'm picky. Got home from a ride yesterday and left signal not working, wire broke off board, noticed LEDs out. It would be a simple fix if I could find some. The UFO light sounds interesting, Where did you pick that up from?
