How does the LED look in the game? I changed many of the 47 and 63 bulbs to LED in my machines and I like the result. I did not even know that they made 12" LEDS.

led tube replacements for common flourescent bulbs are available and cheaper than replacing a ballast.
the gotchas are:
1] some are plug-n-play, but that means you need a working ballast
2] some require you to remove the ballast and wire 120V directly to the tube sockets. This is usually easy as it's often just a case of removing the starter and cutting/splicing the ballast wires
3] some tubes want the 120V wires on the two pins on one end of the tube, others want one wire on each end of the tube. Get it wrong and say goodbye to the 120V fuse.
4] usually inside the tube is just a single led strip and a curved reflector, so the light only comes out in roughly a 180 degree area. A few tubes are more complex and send light out in most directions.
5] some tubes are rotatable so you can aim the light where you want, others aren't. The ones that aren't is usually not a problem as long as you don't install the tube with the light pointing into the back of the game :-)
A tube lighting the reels could be more of an issue ... depends on how the sockets are mounted. You'd probably want a rotatable one for the reels, which also lets you spin it for less light if you want.
