I also got the dome light mounted. The map lights are traditional amber/non-LED bulbs on purpose, I want a less-bright light if my wife uses the map light while I'm driving, and also I have probably a dozen of that kind of bulb floating around. The center I did put an LED into.
It all turned out really well but there was one disappointment. Oh LMC... They sell a "clear dome light cover" for this unit and it was cheap so I got it. But caveat emptor, it doesn't fit very well. It won't stay on, it seems like the cover is just a millimeter off on the width and the mounting tabs are so short they don't grab the slots they go into very well. It's hard to tell from the photo but it's actually hanging down in the back here.
The neoprene gasket did do its job. This is the "wrong" light for my cab ceiling so my mounting boss is a smaller rectangle. I used the gasket both to trim out / fill the air gap where the new light sits on that boss and also make sure the terminals don't contact the roof of the truck. I could have made it about a millimeter smaller all around but it looks fine if you don't look too close.
I had ordered a regular lens for my f250, then saw the clear one from LMC. Bought two, the one in my Bronco works great.
The one in my truck is in the center console. Kept falling out. So I put the original style in to see if it would stay in, it does. I need to put the clear one in the garage as a back up for the Bronco.
Weird, the two bases look the same to me. ¯\_(ツ)_/¯
