UPDATE; BOTH of those bulbs were fried in my HVAC panel so they can go out at the same time (mine were probably due to the short that the crackheads who ripped off/out my head unit caused

). They are a #37 bulb ($1.49 for 2 pack @ Sears Auto),
NOT a #194. They ARE a BEYOTCH ++ to get out of the holder without breaking though. They are a press in type, and I had to use a Craftsman pliers' round jaws part with the bulb wrapped in a rubber "jar lid grip" to struggle the thing out without breaking it!!
