P/W switch illumination

It used to light up in the dark. I notice it doesn't anymore. Pretty trivial, but I wanted to fix it if I could. I took the switch cluster out, but didn't wanna try prying the buttons off to seperate the box. Anybody know if the light is a servicable bulb, or just something soldered to a board? If that's the case, I'll just buy a new cluster if they aren't too expensive.

I have a 92 the wife has a 93 lumina so these two years i know for sure that they are replaceable .the only thing is that living here in canada i could not get them at my local parts store .i had to get them at the dealer. if i'm not mistaken the size for the bulbs is in your manual,if not the dealer will no.and there pretty easy to change.hope this helps.and it's not trivial i myself would rip a whole car apart to get at a burnt out bulb thats my pet peeve in a car.
