Moving this out of the Try Xeenon group thread as it will eventually move on to Centaur (my next project after Xenon).
There's not a lot of options for mods available for the old solid state era so I'll be offering up anything that I come up with for those that are interested.
1st up .... Xenon
Inspired by fellow pinsider dothedoo , I've done my own spin on his idea of extra backglass illumination/animation.
It's a non-permanent mod that only requires some power from the GI rail on the lightboard since it has it's own control board and power rectification and regulation circuit
Mount the lightstrips, control box and clip onto the GI bus wires and you're good to go.
I'm thinking $50 +shipping (from Canada) covers the parts and a couple of beers. PM me if interested.
