I've got a '93 90S with the outside temp display at the bottom center of
the gage cluster (manual trans, so no PRNDL display). AND I can
definitely state that the bulb is replaceable. I have done so.

The very same 60mA 12volt bulb can be used in a variety of places within
the cockpit of the B4 90 series.
1) backlighting for the outside temp display
2) backlighting for the center console switches (emergency, rear
defrost, etc)
3) backlighting for the 4 way switch for the outside mirrors

LEDs can work wonders too.
1) sunroof/moonroof switch
2) window switches
3) replace the red bulbs in the seat heater switches.

I've done it all, including fixing a non-functional rear defrost switch,
the main solder joint in the switch cracked.

It's amazing what a little soldering skill and electrical knowledge can
save you in dollars.
