So I pulled my working-but-dark window switches apart and found a little blown xmas tree light bulb inside. Unfortunately this bulb is hard wired in and has to be de-soldered to be removed. Trouble is, I have no idea what type of bulb it is. Presumably ALFA probably thought people would simply replace the entire switch. I've seen on other forums for different cars (bimmers and saabs) that people use a "grain of wheat" bulb for theirs, will that work okay?
