Quoted from SKWilson:
While I love Comet's products, I am not a fan of their lighted button kit. I did put it on my EATPM, however you need to drill into the cabinet to install the lamp holders.
Sorry, late to the party here. Thanks for the feedback. Yes, you do need to affix the sockets with (included) wood screws that go into the inside of the cabinet. There are other similar screws (from the factory) throughout the cabinet that help to organize the wiring harness. You do not need a drill...putting strong force while turning in the screw with 1/4 hex driver hand tool is enough to get it in.
Also...about the sticking flipper buttons...
This happens on all my modern Stern machines as well. As far as I can tell, what happens is the lip of the button shaft gets a little worn, which enables it to feed into the tube that the lip is there to prevent it from going into. It seems to eventually happen on many of the replacement buttons I've found as well.
The fix is to use a 1/4" e-clip on the shaft of the button, just inside the lip. This prevents the lip from wedging itself into the tube. (Sorry, this is the best way to describe it without pics).
Actually, hang on...I have a pic. I've been doing this on all my NIB Stern machines on location and it's faster, cheaper, and more effective than replacing the buttons. You can do it without taking anything apart.
