OK SO I TOOK THIS OFF ANOTHER JEEP WRANGLER FORUM I THINK IT ANSWERS MY QUESTION
I bought the round 4" LED grommet mount lights from the local Harbor Freight store for $14.99 each (includes wiring pigtail & grommet) and an EL-12 electronic flasher from Napa for $11.99. I stopped by Home Depot for a 2'X4' sheet of thin fiberboard to use as a template.
I unplugged the stock lights from the wiring harness & removed the light housings from the Jeep body. I covered the rear sheet metal of the tub with some heavy fiberglass masking tape I "borrowed" from work to protect the paint while drilling. Behind the light housings are 3 screws (arranged in a triangle formation, 1 to the top, and 2 lower ones) that attach the factory lights to the body, and a large oval shaped hole for the factory wiring to pass through the body. I used the top (centered) screw hole & the large oval hole as reference points for measuring. The left rear light is as low as it can be and not interfere with the gas filler's surrounding trim, and as high as it can be without interfering with the top of the rear wheel wells. The hole required is a 4-1/2" hole and the left one is a tight fit to be high enough to clear the gas filler & wheel well top plate, so I measured the left one first.
I used a 4-1/2" hole saw to cut out a hole in the fiberboard, and used the round cut out disc piece to hold up to the tub & find my center drill point. After drilling out the sheet metal I installed the grommets & wired the lights (green/black stripe factory wire to red brake/turn signal of LED lights, and the solid white factory wire to the black LED park circuit of the LED lights) and popped them in the grommets. They look AWESOME in my opinion!
Now before anyone asks, I have not yet installed my 2" LED side marker lights, and no, I don't have a license plate light or backup lights either. I plan on wiring (through a relay) some low power flood/driving lights up for reverse lights, and I also plan on using a license plate frame with a built in light to address the plate light issue.
