I made the mounts for my 54" curved light bar, as I didn't much care for the ones I saw on eBay.
I can't argue with
@DaddyDubbs, a high mounted light in rain, fog etc. is a non-starter. But, for all other more clear lighting situations, a high mounted light gives better useful range and better perspective. It is more labor intensive to install, though I think for sure worth it.
I did a write-up on the install, posted a couple of years ago. The 1/4 - 20 bolts go into rivet nuts in just one side of the roll cage corner gusset. The ones I saw elsewhere used longer bolts through both sides of that gusset, but I thought the added clamping pressure on the gusset not the best way to go. What I did works well, it's solid, doesn't vibrate, and holds adjustment.
