Whether there was a collision or not is wholly irrelevant.

The relevance is the misunderstanding the device can cause, under certain circumstances and I think these circumstances are not individual to what I saw yesterday.

I expected this to happen actually, and will do every time I sit there waiting for a gap now.

I can tell you truthfully there was about a 3-4 second space between the car going under the bridge, and the lights coming on, which coincidentally was when the car existed the darkness area. So the whole illumination sequence was not only misleading, but further to that, pointless.
