Traffic Light Manufacturers Are Making an Impact With LEDs

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! We must thanks to the traffic lights manufacturers.

Nowadays, the traffic light is one of the best, especially the LED traffic lights. Even though the most common colors in traffic signals are red, yellow, and green, their meaning might vary, depending on the particular country we are referring to. The red color is associated with the word "stop" and this is the case almost everywhere. The color could also mean something like a closed road. The yellow, which is commonly found between red and green, means that you should get ready for the green color about to turn on, and it will be your turn to move. The green color gives you permission to drive ahead or cross. Red and green colors are usually the ones that last for a longer period of time, compared to yellow.

In some cases, you might have to stay at the stop light for five minutes or more when the red light is shining. This is usual when construction work is done around the road. Some countries have the practice to turn off the red and green in the night until the morning, and leave everything to the yellow light and the traffic signs. This is effective in towns and cities with smaller populations and less traffic.

Nowadays, it is impossible to find a traffic light that does not have an arrangement of LED light bulbs – all credit goes to the traffic lights suppliers. Halogen or incandescent bulbs were the most common ones found earlier, but the recent trend shows that the number of LED is steadily increasing everywhere each year. Halogen or incandescent lights are known to work for a shorter period of time and the intensity of the light is not as powerful as the LED. However, when LED was first introduced, there appeared one significant problem. In the midst of a heavy snowstorm, people in traffic might have problems to see which color is shining, since LED does not produce enough heat to melt the snow, unlike halogen or incandescent lights. Nevertheless, the advantages of LED are too great to go back to the predecessors. LEDs are also found in traffic countdown timers as well.
