I have not. But I'm very familiar with the bumper. It's essentially 3/16" rectangle tube with a couple of shackles frenched in and some channels for mounts.
I put a pod light on my spare tire. It was simpler.
If you're thinking about cutting a hole for some square or rectangular flush mount LEDs you either will need to get ones shallow enough to fit inside and cut the face of the bumper...or cut all the way through and box in the cutout.
Either way it's a very minimalistic bumper and you're going to have make holes and modifications carefully.
