Great lights. Use the KC wire harness, it’s a lot more heavy duty than the procomp harness. I have 4 trucks, 2 sets of these and 2 sets of ARB Solis 9” and the Procomps give them a run for their money

We use these lights on our Spec Trophy Truck, they work great blasting through Baja at over 100 mph in the dark. The housings are aluminum and mounting brackets are stainless steel, connectors are weatherproof. Really nice piece.

Just installed yesterday on my '18 JL Rubicon. Mounted to steel front bumper. Very impressed with this light so far. They are very bright, I went with the 5" size which are plenty big enough and bright enough. Well built and come with VERY beefy mount brackets. Will update review when I get a chance to spend more time out in the boonies with them while driving. Four stars at the moment only because they should come with covers/shields. These do not come with a wiring harness BUT do come with the all weather plug and only requires you to supply the final wiring from the plug/ lights to the power source (there is a harness available separately from Procomp).
