Just to clarify, the rig is not mine, but one I built a little over a year ago for Mtfit who is also on this forum. Thanks for the compliments, Bill and I were both very happy with how it turned out.
The side markers are repros for a 69 Mustang. I choose these becase they fit the existing holes but are smaller overall size (just need to drill new mounting holes a bit closer) and have clear lenses. I like adapting FoMoCo parts and more specifically retro FoMoCo when I can. I then installed some LED bulb like are also installed in the tail, reverse, turn, license plate, glove box and dash locations.
The front and rear rock lights are just some inexpensive low profile lights I got from Autozone. IMO, LEDs could not match the amount of light I wanted. They light up the rocks very well for a spotter and will provide nice lighting if you'd need to fix a drivesahft or other part on the trail at night (I see from the rear Rock Light pic that that series of photos was taken after Mtfit took delivery and had already gotten all my hard work muddy

).
I also used these same lights for added reverse lights which I made oval cutouts in the face of the rear Protofab bumper for. They looke real nice and are well protected and very bright which helps sinced we also installed the tinted soft top which makes it hard to see at night.
