Quoted from DiggerPSU:If your so inclined while your workin on the cab you might want to think about replacing the start button with an Angle Eye lit metal start button. I put them on 3 of my games and they really look cool. They are 12v but still light up nice with 6.3v from the coin door bulbs. You need a 22mm diameter one and can get them on ebay.
Yeah I posted that and it works perfect, don't see why it wouldn't work for you. The only problem I ran into was that the lit button wasn't long enough for the nut and washer to attach on the inside of the cabinet so I had to make the hole on the inside bigger half way through the thickness of the plywood.
