The P.O. added them to my truck, I replaced the bulbs and lenses with the Recon tinted lenses and amber LEDs. The LEDs need a very good ground or they are dim. P.O. didn't add any silicon or touch up paint when he drilled the holes for the screws and even though I'm in the desert SW, there is still some bubling around the holes I saw when replacing the lights
I did 5 rocker lights on each side, each one mounts in a 3/4" hole and uses a rubber grommet, each has 3 LEDs. There's a thread titled "chicken lights" and there were alot of pix.
