Does anyone know how to power/control it? Just supplying 12 volts doesn't do anything.
I'm thinking you're talking about the diagnostic LED flasher. It was connected directly to the IFI robot controller's "team color" pins. I don't know if the driving circuitry was documented anywhere, but it's possible hooking 12V directly would fry it.
