The inputs of traffic lights typically include vehicle and pedestrian detection systems, which can consist of sensors like inductive loops, cameras, or infrared devices. These inputs help determine the flow of traffic and pedestrian demand at intersections. Additionally, timers and manual overrides can also serve as inputs to control light changes based on pre-set schedules or emergency situations.
It is not really a circuit, traffic lights in todays world are controlled by programable logic controllers or a plc. There are rungs of logic to control the changing of the lights which are known as the inputs and outputs where the voltage is controlled to change the lights from red to yellow and green.

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.

No, because traffic lights are charged, not naturally bright.
Traffic lights are made of part metal and part glass.
people can be colorblind. When the power goes out so do the traffic lights.
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.
As of 2011, there were more than 25,000 sets of traffic lights in the UK. There was a 30 percent increase in traffic lights from 2000 to 2008.

Some lights have sensors :)
