I have something that is the same from a different company with superbrite blue and clear buttons.

I just soldered mine by tracing the wire from the coin door light on my Star wars trilogy further into the cabinet and stripped the wire then heat shrank for safety again... Funny enough during game play they flash on off and on so that was a bonus.

Just cut the plug off, solder wires together as + and - then multimeter the + and - on the coin door light and you are good to go!
