A way to find out its to call all the factories that manufacture traffic lights and see the sales reports of each country since 1912 when the first traffic light was created by a police man.

There are many ways you can design a simple traffic light circuit. I recommend you to use a 4017 IC. Please check this site as reference. It's a two way traffic light circuit. http://circuitdesolator.blogspot.com/2011/01/traffic-light-circuit-based-on-4017.html
The opposite would be "light traffic".

If a traffic light breaks most cities will assign a traffic cop to regulate traffic until the light can be fixed.
It did change the wrold alot because we didnt have traffic lights and there would be alot of accidents and when they invented the traffic light they could get around easier and it made it safer
Generally, traffic lights take about 5-10 seconds to change to a different color. This timing can vary depending on the intersection and the traffic light's programming.
A traffic light in Jakarta, Indonesia has a 300-seconds timer. If you are unlucky you have to wait for 5 minutes there. A traffic light in Sofia, Bulgaria at an intersection between a main road and a small one used to be constantly red for the cars coming from the small one. The only way to get a green light was to get out of the car and press button for pedestrians. The traffic light was repairer 5 months later.
A traffic light you seen change to green
your not so bright
Yes. That is why they are called traffic lights.
