On December 10, 1868, an engineer name J.P. Knight first installed the traffic lights at British houses of Parliament in London.
No, traffic lights are typically made using light emitting diodes (LEDs) or incandescent bulbs. Gallium is commonly used in LEDs to emit light in various electronic devices, but it is not the primary material used in the production of traffic lights.
Yes, the word 'traffic lights' is a noun, a plural, compound noun; a word for things.
Yes, Milan (Milano) has traffic lights, including red lights at intersections to regulate traffic flow.
Lester Wire did not invent traffic lights. The modern electric traffic light system was invented by Garrett Augustus Morgan in 1923.
Traffic lights provide visual signals to regulate the flow of vehicles at intersections. They indicate when it is safe for vehicles to proceed, when to stop, and when to exercise caution. Following traffic lights helps to ensure traffic safety and reduce the risk of accidents.
Traffic lights are made of part metal and part glass.
The usual part of the traffic light is made of metal and the lenses are made of glass.

No, traffic lights are typically made using light emitting diodes (LEDs) or incandescent bulbs. Gallium is commonly used in LEDs to emit light in various electronic devices, but it is not the primary material used in the production of traffic lights.
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.
The new traffic lights are now LED lights and do not ever burn out.
Yes, the word 'traffic lights' is a noun, a plural, compound noun; a word for things.
No, because traffic lights are charged, not naturally bright.
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.
