If you want to fall back in love with playing any of your pinball machines, just add in LED's. That is my main additction now is populating my machines with. They really brighten up dark spots, especially in the Twilight Zone and the Star Trek Next Generation machines. You may just want to start off with just replacing the general illumination. I've used 100's of the Ablaze 3-LED's from Pinball Life. There is no other one I've seen this bright for the GI. Install a few, you'll see what I mean.
