I've noticed that in some parts of London recently- especially in the Camden area, there seem to have been added strings of bright, small blue lights- one adjacent to each lamp. Does anyone know the purpose of these lights?

Cameras that use the blue lights for night vision.

Blue lights are mounted to the backside of the traffic light fixture. When the front side of the traffic signal goes to yellow from green, the blue light goes on. Now, when a motorcycle officer is waiting on the backside of the intersection, he can tell which cars are going through the intersection AFTER the traffic light has gone to yellow.

They just added this in Simi Valley just outside of Los Angeles. It is used by the police to nab red light runners...
