I acquired two new sets of fog lights recently. I have always wanted to put some lights underneath to spot with at night so I went for it. I mounted two lights on each side of the frame back above the middle of the driveshaft. I pointed them across from each other so that they were able to project light further. Then in the rear I put one pointing forward from the rear and then I put the other one pointing rear from the middle bed rail.
They sure do a good job showing me whats under my truck at night. Now when I'm rolling around at night and need to spot whats under my truck it's no problem. Plus I have very good light while backing up
I'll get a picture to post later tonight when it gets dark.
