A question about the traffic lights:
I've noticed that some lights have a board with a white lining on its
edges, whereas others do not.
What's that about?
It was a design of traffic light introduced years ago, presumably in order
to make them easier to see. Evidently it wasn't found particularly
useful, as the requirement for the white-edged board was withdrawn. But
some lights still have them. They have no legal significance compared to
other traffic lights.

I see. I was just wondering if it meant that some could be manually
controlled, while others were completely on time automation.
