Who Makes Traffic Lights: The Major Distributor

When you’re driving, have you ever wondered who makes traffic lights? You know, those big red and green boxes that control the flow of traffic? It turns out that there is a major distributor who makes traffic lights and controls their operation.

Who Makes Traffic Lights?

Most people take traffic lights for granted. They are always there, telling us when to stop and go. But have you ever wondered who makes traffic lights? The answer might surprise you. One of the leading manufacturers of traffic lights is GE Current, a subsidiary of General Electric. GE Current has the legacy of General Electric selling more than 10 million LED signals worldwide.

GE Current traffic signal solutions are known as GTx LED signal series. GE Current continues to develop a traffic signal family with high-quality, energy-efficient, and sustainable solutions that meet the needs of cities and towns around the world. 

What Are Traffic Lights Made Of?

Traffic lights are one of the most common sights on our roads today. They regulate the flow of traffic, ensuring that drivers and pedestrians can cross intersections safely. But have you ever wondered what traffic lights are made of? The answer may surprise you. The new traffic lights you are seeing installed are made of an array of LEDs. Each LED is about the size of a pencil eraser. 

The LEDs are mounted on a circuit board, which is encased in a clear plastic housing. The housing is then attached to a metal pole, which is raised above the intersection. This design makes traffic lights more visible and reliable than older models that used incandescent bulbs. 

What is the Power of Traffic Lights?

At first glance, traffic lights may not seem like they use much power. However, when you consider that there are approximately 300,000 traffic signals in the United States and that each signal uses an average of 100 watts of power, it becomes clear that traffic lights have a significant impact on energy consumption. While the traditional incandescent halogen bulb is very energy-intensive, the LED traffic signal bulb uses only 15 watts of power.

As a result, the switch to LED bulbs has the potential to significantly reduce energy consumption and help to reduce greenhouse gas emissions. In addition to being more energy-efficient, LED bulbs also last longer than traditional bulbs, which reduces maintenance costs and helps to further reduce energy consumption.

How Do Traffic Lights Affect the Traffic?

Traffic signals are an essential part of the infrastructure that keeps our roads safe and moving. By regulating the flow of traffic, they help to reduce the number of conflicts between vehicles and pedestrians and minimize the risk of accidents. However, traffic lights can also have a significant impact on the flow of traffic. When a light turns green, it provides a cue for drivers to start moving. 

However, if the light is not timed correctly, it can cause vehicles to bunch up and create congestion. Similarly, red lights can cause delays if they are not coordinated with the flow of traffic. As a result, traffic lights can have a major impact on the efficiency of traffic flow. If they are not properly managed, they can create gridlock and frustration for drivers.

What Triggers a Traffic Light?

Most traffic lights are triggered by active infrared sensors. These sensors [1] emit low-level infrared energy into a specific zone, and when that energy is interrupted by the presence of a vehicle, the sensor sends a pulse to the traffic signal to change the light. Active infrared sensors are typically used at intersections with high volumes of traffic, such as freeway on-ramps and off-ramps. 

They are also used at intersections where it is difficult to install inductive loops, such as curved roads or roads with underground utilities. While active infrared sensors are the most common type of sensor used to trigger traffic lights, there are other types of sensors that can be used for this purpose, such as microwave sensors and inductive loop detectors.

How Do Traffic Lights Improve Road Safety?

Traffic lights are an important part of road safety infrastructure. They are typically positioned at intersections and crosswalks, and they help to control the flow of traffic. By regulating the timing of when cars can enter an intersection, traffic lights can minimize the chances of a collision. In addition, traffic lights can also help to prevent congestion and gridlock. 

By keeping cars moving at a steady pace, they can help to reduce the frustration and impatience that can lead to aggressive driving. As a result, traffic lights play a vital role in keeping roads safe for both drivers and pedestrians.


Now you know who makes traffic lights and what they’re made of. You also understand how traffic lights can affect the flow of traffic and how they improve road safety. Knowing all this, the next time you’re stopped at a red light, you can take a moment to appreciate the technology that’s helping to keep you safe.
