Lit Flipper Buttons

Decided to light the flipper buttons on my LOTR LE.  Wanted to use red buttons, but didn't have Red Transparent buttons on hand.  Only Dark Blue, Green and an orange-amber color.  In the end, I found some clear buttons and lit them with high intensity Red LEDs.  It was that or use color changing LEDs, but I have a few of those on the game already (Palantir and Start Mode).

BTW the Pinball Center Noflix Plus Color changing LEDs are fantastic.  I used the Superflux #555 base on my Mode Start and liked it better then any other brand I have tried.  The colors are more distinct and no strobing effect, so well worth any extra cost.  Same for Noflix Plus Warm White.

This is what the transparent buttons  look lit by Red LEDs:

Here are some other color choices:

I used a nice circuit board, you can also do it with #555 bulb holders but this provides two LEDs on one power input terminal and simplifies the wiring.  Top are fully built and bottom are the bare PCBs.

An example of it fitted under a leaf switch:

I found an unused connector (3-pin molex) on the right hand side with the two outside pins at +12v and Gnd,   which was perfect.  You would need a Molex connector, pins should be .093".

Here's what it looks like installed inside my game:

You do get some "bleed through" where you see some LED light from under the playfield, but that's why red is a good choice.  Stern uses visible red LEDs all over the game for trough and VUK optos.
