I used some speaker screen that I bought from Marco. I cut the screen to the speaker outline. I glued the led rings(I forget the size) to the center of the screens. To power these I simply use a separate wall plug 12vdc, 3A power supply. I plug the game and accessories into a smart power strip. When the game is turned all of the accessories, speaker lights, undercabinet leds, topper, all turn on. When the game is turned off the accessories turn off. I have used the Pinballbulbs kits on other games and they work great for the games they are designed for.
