Here you go. I can't weld, so I spent $20 bucks in material, and bought beer and pizza for my bud who can weld. We extended the support for the spare tire and put a "shelf" on it. There I mounted two back up lights. They are switched and run to the reverse light as well.
There is space between the top of the tire and the light shelf, as that was intentional. The YJ will be going to 33's and then the space will disappear.
