I have seen many techniques for installing lighted flipper buttons. Although they all produce excellent results, I decided to try something different tonight. I'm not saying this novel approach is better or worse, just wanted to share my results. Note, this is just a draft document. I can include more detail if there is any interest. All in all, it worked really well.

Step 1: Cut/Dremel a small slot into the bottom of a transparent flipper button (note: I purchased mine from Pinball Life).

Step 2: Insert a mini led into the bottom of the flipper button (note: I used 3mm leds that I purchased from RadioShack)

Step 3: Insert some heat shrink tubing to cover the longest lead (trim to fit) and bend the leads into the grooves you cut in Step 1

Step 4: Solder speaker wire to each lead and cover with heat shrink tubing. Repeat for both flipper buttons (note: make sure to cut speaker wires to correct lengths for each button)

Step 5: Install flipper into each side of machine.

Step 6: Make a Molex connector that can connect into the coin door board (+12V/Ground). (note: make sure to put in the proper in-line resistor for the leds)

Step 7: Enjoy your new lighted flipper buttons.

It took me a couple hours but i was figuring it out as I went along. My guess would be an hour if you are proficient at modding stuff.

Hmmmmmm.....never knew there where rubber rings around the plunger piece. Just make sure you run the led wire through the rubber ring before hooking it all up.
