Occassionally I've forgotton to switch them off when issuing a line up clearance and the pilot has gone straight across the red bars, it makes you wonder if, when in a car and they were stationary at a red traffic light and their passenger said "nothing coming either way" they'd drive straight across the junction.
Certainly it's not an accepted procedure in the UK (crossing red stop bars or traffic lights), and the only time it might happen is if the lights couldnt be switched off for technical reasons.
