Hi

Ok...Based on what we've discussed, here's what I've come up with so far. See attached

The circuit is designed to drive relays. I thought about SSR's but I though they would be too expensive since we would need the ones that have a DC control but support an AC load. But its up to you.
I've also added a lamp test function. The lamp test button would be on the Gamemaster console. When the lamp test is pressed, the audience lights will sequencially light, G->Y->R, one at a time (for 1 second) for each box starting with light box 1, then light box 2, etc. The sequence will continue until the RESET button is pressed. This will let you test the bulbs one at a time.

Let me know what you think.
