We have large red lights over the door to the live room, both outside in the corridor - so people don't blunder in or start making loud noises during a take - and on the inside, visible throughout the live room and from the booths. There's also a light in the control room just so we know the system is working! The lights themselves are mains bulbs, driven by a solid state relay which in turn is switched by the gadget. It's configured to flash when any track is in record-ready and be on when Pro Tools is in record.

I have considered adding a third display to the computer and mounting it on the wall in the live room, mainly to show the big counter window. But it's not clear to me how I could use this to provide a high-visibility "recording" signal.
