Quoted from Lame33:I was really excited about the colordmd kit until I learned that you lose game functionality unless you permanently mod the pin for the number lights. Given my soldering skill are about at the level of untrained, one haned monkey, I've lost most of my initial enthusiasm for the kit. (At least until I can improve my skills beyond slather a bunch of solder to replace a flipper coil) It's too bad they don't offer a replacement compatible lighting part as an additional purchase.
Suggest contacting Rob Anthony (Borygard) or Kris Bliznick (Firebird Pinball) to see if they could make the board changes for you. The board changes are 100% reversible.
