If you have high output LED's, you can drill a hole at the bottom, either side of the microswitch just big enough for the top of the led to go through, and hotlglue 'em in there. That's where my standard leds mounted on my Electric ICE buttons from GGG. I'm using one for power, and I THINK I'm going to use another 2 for player1 and Player2 start, the power one has a dual-color standard LED from a PC case in it, green for PC power, amber for sleep...
