Truth or lie? Double flashing your car's headlights can turn a red light into green.

There are different types of traffic lights, some of them can change color from red to green when certain lights are detected. However, here we will tell you what these lights are and how to change the signal of a traffic light when you need it.

It has probably happened to you sometime that you are driving in your car and feel like you have stumbled upon all possible red traffic lights. The worst thing is when you sit at a red light and patiently wait for it to switch, but it takes too long.

Instead of waiting, it has become popular to think that flashing high beams can cause a red traffic light to turn green faster than usual. But is this really true? To find out, we first explain how traffic lights work.

How do traffic lights work?

It is important to understand how traffic lights detect your car when you approach them. According to WikiHow, there are three different methods by which a traffic light can detect a waiting car:

1. Inductive loop detector: When approaching a traffic light, look for the markings before the intersection. These marks usually indicate that an inductive loop detector has been installed to detect conductive metals in cars, bicycles, and motorcycles.

2. Camera detection: If you have ever seen a small camera at a traffic light, this camera is used to detect cars waiting for the traffic light to change. However, some of them are there to spot red light brokers.

3. Fixed timer operationor: if the traffic light does not have an inductive loop detector or camera, then it can be activated by a timer. These types of traffic lights are usually found in areas with a lot of congestion.

Can you make the light turn green by flashing your high beam?

Unfortunately no. If you've encountered a traffic light that uses camera detection, you might think that quickly flashing your car's high beams can speed up its switching. However, it is not. cameras traffic lights programmed to recognize a series of trigger flashes fast, the speed is equivalent to 14 flashes per second.

So if you can't do as many flashes per second as an experienced high beam car, you'll have to wait until the light turns green on its own. Traffic lights are primarily programmed to change at will for emergency vehicles such as police cars, fire trucks, and ambulances.

What can you do to light green?

The next time you get stuck at a stubborn red light, make sure your car is correctly positioned to face the intersection. After making sure that your vehicle is correctly positioned above the loop detector or in front of the camera, you will activate the traffic light to detect that the vehicle is waiting and it will begin to change.

There are several devices on the market known as "Mobile Infrared Transmitters" (MIRTs) that you can install in your vehicle and effectively change traffic signals faster by simulating the flashing lights of ambulances. However, these devices are illegal and if you are caught using them, you can be fined or punished accordingly.
