Traffic lights change color using a timed sequence set by programmers. Typically, they cycle through green, yellow, and red to control the flow of traffic at intersections. Sensors or timers can also adjust the timing based on traffic conditions.
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.

Yes, the word 'traffic lights' is a noun, a plural, compound noun; a word for things.
Inside a traffic light are control circuits, LED or incandescent lights, and a timer mechanism. The control circuits manage the sequencing of the lights, while the lights themselves are responsible for displaying red, yellow, and green signals. The timer mechanism ensures that the lights change at appropriate intervals.
Traffic lights work on a timer, but if you look closely on the road when your stopped at the traffic lights, you should see a rectangle like shape under the car it is called a sensor And when you drive on it, a signal is sent, so the timer knows a car is waiting, if no other cars are going the other way, the timer will change and the light will go green so you can go. I hope this answer helps.

No, Flashing your headlight's will have no effect on a traffic signal. The reason a traffic signal changes for emergency vehicles that have the lights flashing, is, they have a special transmitter that tells the light to change. This transmitter is connected to the emergency lights so it comes on when the lights are used.
