Can anyone help me ID the bulb type and part number for the older style AC button?

Its very small, and looks similar to the antenna bulbs, but I'm not 100% sure they are the same (type B 84999-10410 ?). Its in my 1991 LC. Apologies, I just dug through 22+ pages of the Definitive LED thread for info, however most of that info seems to pertain to the newer, electronic climate control system, not the manual style.

Looks like the antenna bulbs, but I didn't take precise measurements when I had the dash open.

A couple of more photos. It appears the bulb base is almost the same as the antenna bulbs (type a), but slightly a shorter bulb. Im guessing they are probably interchangeable, but it would still be great to pull a part number. Any way to tell from the markings on the base? I can't find it any breakdown diagrams at all.

I had a spare antenna bulb, and put it into the AC button. Works. Might not be quite the right power output but it works! Here are some more pics for history's sake:

Found this one today finally on partsouq. 88607-16010

I've just been running the same bulbs as the antenna switch in this button. Seems to work fine. Will upgrade everything to LEDs here soon.
