anyone know if they take the same bulbs as behind the HVAC *****?

I have a light out (4wheel HI LOCK).

I used these bulbs from superbrightleds.com for the HVAC illumination, but curious if same bulbs are used for the locking control panel.

They are not the same lights. And unfortunately, they are not a socket design; they are soldered direct to the board.
When I had a light go out on me (4-HI), I moved the light from behind the diff-lock area to the 4-HI spot. My truck does not have a locker, so I obviously did not need that light (they must all have the standard electronic board, with a different button face).

In your case you don't have that option, but perhaps you could get one from a local junk yard? You will need to de-solder and re-solder the bulb in place.
They are tiny blue lights with very small wires. think of a (much smaller) Christmas tree light bulb (the old ones you could replace).

EDIT:
was able to find a picture from another forum (Serv 4wd | Hummer4x4Offroad)

 

Uggh...dang it.

Wish I knew what bulbs they are and I'll try to de-solder, re-solder a new bulb.

 

Probably can be found here, but no clue which one to get:

Interesting. This other thread shows they look a bit different:
