Quoted from CLEllison:

Pulled the trigger on full LED conversion. Installed the LEDOCD and the Gizmo board. After installing the Gizmo board I had several lights stop working. I tried jumper settings and to no avail. Pulled it off and lights working again /shrug. Anyway trying to not make this a clown puke mess I used green, red, yellow and white. Creating contrast best I could. The difference in being able to see the ball is astounding. Literally had the best game ever. Collected 10... yes 10 gifts, dtr beaten twice, beat TT and beat FOTR once. Freaking could NOT beat ROTK. Let TABA time out. 3 attempts to beat ROTK. End of game. I ran into a code bug after getting past collecting all the gifts. When you collect the "7th" gift all gift lights stay lit so you have no idea what you're given (which sucks because you cant smack sam around to change it). After I lost the ball then the gifts reset to normal. /shrug
Here's the list of what I used for LEDs.
I had way too many white 555s so you can drop that to maybe 75? Left 906 bulbs as incandescents.
Comet pinball is the source (cheaper than their kit). All standard LED type and LEDOCD board (ordered from Herg)
100 white 555 (super bright clear natural white)
6 green 555 (frosted)
7 green bayonet (clear)
12 yellow bayonet (clear)
10 red bayonet (clear)
20 white bayonet (clear)[quoted image]

Quoted from DaveH:

If you LEDs the game, LEDOCD the game as well. This isn’t something that needs a lot of thought. LEDs suck without it, and with it, they are beautiful. Even cheap LEDs will look good.
As for PinSound, the news isn’t as good. I bought a few PinSound boards, and I LOVE them in 90s games like BSD and Getaway. But I just didn’t like it in LOTR. Now I realize a huge part of that is how much I like the normal calls of LOTR, and I’ve owned the game twice. Something different felt odd. So I ended up pulling it out of LOTR. Just one guys opinion.
