it is just some diamond mesh that I welded inside the bumper,,,the way my lights are mounted are different that the kit that comes with the light,,,instead of using the plastic spacers, I used a piece of one inch sq. tubing,,,, and sloted the holes so I could space them back just a hair,,,,that way it leaves room for the diamond mesh,,,,,,,, be prepared to paint your bumper if you do it,,,, even just tacking it for a split second will bubble the paint,,,,,, good luck,,,, ,,, ,,,, ,,, cg
