I'm sure you can dude. I took out my guages to change the gas light. Eventually you get to a point in which there is a large circuit board with small LED's soldered to it. You can probably buy blue LED's at either Radio Shack, or somewhere on the net, and just replace them. I know for a fact that you can change the Lights for your heating/air section... Cryogen97 has the DIY at his site... at the moment. Someone else will post the link or I will get it when I get home tonight.
