Should be able to. Are you talking about the lights inside the instrument cluster and the HVAC control panel?

Actually, the 2000+ Bonnevilles have one resistor that melts and then causes most of those lights, if not all of them, to go out. Replacing that relatively commonly dead resistor can bring all your lights back to life.

Well, that might depend on what year his car is.

If its 99 and below, the instrument panel lights are the twist in/out socket bulbs.

His profile shows he has a 2000 Bonneville. I'm going solely off of that.

Hey, welcome to the forum! I'm not sure about where it is, but you should find it if you feel like taking apart your dashboard. You should clearly see one blown resistor that'* huge and ceramic coated.

Where do you get the new LED'* from? I have a 2006 Sierra with 2 lights out on my HVAC and it bugs the crap out of me. Are you able to take the units apart with out braking things?
