White Square Boxes above traffic light
Options
I have just seen on the A1108 Earlham Road, Norwich at the five way roundabout two white Square Boxes above pedestrian traffic lights each facing in line with the traffic.
I have never seen these before and wonder if anyone knew what the are?
I suspect they are for the emergency services to change the lights but I am not sure

Radio aerials.
They allow the lights to communicate with emergency vehicles, the control center etc.
The traffic sensors are the thingys that look like a floodlight with black glass.0 -
Wrong thought detectors, put there by the thought police.

Seems they are called magnetometers, they are used to monitor traffic flows and as an alternative to induction loops in the tarmac.0 -
