So for a while I've been putting up with my power window switches and 4x4 push buttons not lighting up at night anymore with the rest of the gauges and switches in my 1999 GMC Jimmy. Now i'm tired of it. I know that these switches use small LED bulbs but I have no clue how to change them or where to get replacements.

I'm also thinking of changing all my switch, button, ****, and gauge lights to blue instead of the boring gm dull white. Does anyone know where to get these LED's, how to change them? And also if anyone knows where to get all these lights in blue that would be some helpful information.
