The red traffic light is the simplest of instruction in our life. As soon as you see it, the body reacts automatically. There are many types of traffic lights to guide cars and pedestrians on the road. What would the World be like without the red light? It would be in complete chaos. The simple invention has brought so much order and safety to the civilized World!

Traffic lights could be the one you angry at when you are in hurry but you have to obey the rules. All countries have traffic light controller, but the rules and the arrangement of the lights are sometimes different.

The term “traffic control” itself varies in many countries. Some call it traffic lamps, and others call it stoplights, traffic signals, robots, traffic signals, etc. No matter what terms people use to name this device, they always refer to signaling devices function to control competing flows of traffic which are positioned at pedestrian crossings and road intersections.

The meaning of these three lights is the same in many countries. The red prohibits drivers to make any moves with the vehicles, the amber alerts drivers to get ready to stop until the red light turns on, and the green allows traffic to proceed in the direction denoted.

The length of each light to turn on is different. The amber light has the shortest time as it just functions to alert drivers to be ready to stop. It usually takes 3 to 5 seconds. On the other hand, the time for the red and green light is longer, and it depends on a road density. If a road has high traffic flow, the red light can take up to 90 seconds while the green only takes one-third or even less.

Until now, there are many traffic violations that happen every day. For extreme cases, it even causes accident, as some drivers usually speed up when the amber light turns on. They crash the vehicles in front of them who have already stopped and. It is all caused by lack of disciplines in riders’ mind.

The role of traffic signal controller. is invaluable in many circumstances. However, today with the introduction of LED traffic signal control things have turned out to be much easier than ever before. Traffic signals made of LED are so effective and durable compared to their incandescent counterparts. They last 10 times more than the traditional form of traffic lighting.
