For anyone stumbling across this in the future....
An S/S+ payline light module will
not directly replace the one for the M. There are two primary issues:
1) Fit - the S/S+ module is
far too wide. It interferes with the left reel window as well as the reel itself. You
may be able to modify, but I have not yet tried this.
2) Voltage - The 1,2,3 feed from the lighting stepper is 12V. The regular setup of the S/S+ payline light module is ~7V. You can simply change the bulbs, but if you don't you'll have a little surprise the first time they try to light.
