I have just spent a little time on a bracket for my spot lights, I went a diffrent route and used a piece of round bar same OD as the rest of the front end stuff. I used a pipe bender to shape it the same profile as the front light surround and with a tab on each end for the lights. The bracket will pinch onto the two bars that hold the front light on. I will post some pictures when i get to putting it on dont have time just now off for a few days to amsterdam.

Cheers

Jim
