Diverging slightly, hypothetical question:
How about a simple red / green traffic light at a runway holding point for control of non-radio vehicles.
If a vehicle is given a positive clearance to cross an active runway at one of these holds on the RT, would you still select the traffic lights to green while they crossed?
Would it be a bit OTT to have to give them a clearance on the RT, then switch the lights to green and then have to watch them until they're past the lights so you can put them on red again.
or
Would it be bad form to instruct a vehicle to go through a red light?
