No one really controlls the traffic lights. A computer system controls the traffic lights, and no humans are involved with controlling the traffic lights day in and day out. It is all automated these days.

Yes, "traffic lights" is a noun phrase. "Traffic" is a noun, and "lights" is a noun used as a modifier to describe the type of lights.
No, because traffic lights are charged, not naturally bright.
people can be colorblind. When the power goes out so do the traffic lights.
Traffic lights are made of part metal and part glass.
Logically, unless there were reasons to control traffic, there would have been no reason to create or install traffic lights. Because "traffic" generally comprises vehicles (motorized or otherwise), the traffic was probably there prior to the lights. Certainly, there were mechanical traffic signals that preceded traffic lights, not to mention traffic officers who once stood at busy intersections to direct traffic on a regular basis.
There are approximately 33,000 traffic lights in the UK. However, this number may vary depending on new installations or removals of existing lights.
