Don't laugh but as bad as I can't stand Ruff Country these lights look to be built pretty well for the price. A buddy bought some for under carriage lighting and they looked like they would fit nicely in my new bumper. They come with a full wiring harness, switch, and universal mounting brackets for mounting where every you want. Found on eBay for $39 bucks a couple weeks ago.
Edit: they are made out of an all aluminum housing also.
