I rednecked mine. I don't have any close-ups, but all I did was run the bolt right through the mount on the light. The mount on the light fits real tight around the bolt, so it doesn't move. I've hit a few small jumps, and been through lots of rough terrain, and they never moved. I guess if you wanted to, you could do what I did, and put spacers in there. Just so you can tighten it down real good. You can pick up spacers at the hardware store, and just cut them to length.
