Here's how I had set mine up.
Fog lights. They were mounted on a pair of L brakets made from 2"x2" aluminum. There was a slight offset (about 1/8") made in the bottom section just below the bumper to clear the splash apron. The brakets were directly bolted to the apron behind the bumper.
I don't have a good picture of what it has now, but the new mounting is very similar. The new one is a 1 peice design, rather than having separate mounts for each light. It's more stable, the lights do not bounce around as much. I'll see if I can get some pix up of it for you, right now I really can't get to the truck to get a good shot.
