I have em on mine, they were there when i got it. Leak like crazy
X2 I had after markets on my last truck and the headliner got a good dose of salt in the winter... plus the roof rotted out under a few of em. Had one fall off on the highway before I noticed the drywall screws. I don't even like the idea of them factory installed. The new Cummins dullys have them and I've read a few reports of them leaking.
If you really want cab lights get a visor that has them. Much cleaner install. Less drilling and the mounts are not on the top of the roof.
