I've got a set of the oval LED lights. I installed one of them in the custom 1/4" thick rear crossmember. It took forever for me to hole saw and grind through that crossmember for the one reverse light that I never went back to do the other. But its one of the trickest looking reverse lights you'll find on the trail
I know I may be late with this but... I picked up some livewell lights that flush mount in a boat livewell. they are 1.25 dia. led. drilled them into the rear bumper and they look really sweet. I'll try to remember to snap some pics.
BassPro Shop, If I remember correctly they were about 20.00 each. the nice thing about them is they are totally sealed units. the not so nice thing is if you are wanting to really SEE behind you they don't "reach" very far.
