This is only speculation, but I would guess that IFI leaves the lights on - they aren’t hooked up to Relay or PWM outputs, and thus aren’t subject to being disabled.
Am I also correct in saying that the lights flash diffrent patterns depending on what part of the match in currently bieng played (auto mode, driver mode, when the match over, and before it starts), and when you are teathred? I believe this is right from my observations during the weekend.
