How To Trigger Green Traffic Lights

Trigger the traffic detector with a common item. Great for motorcycles, bicycles and scooters! Trigger the traffic detector with a common item. Great for motorcycles, bicycles and scooters!

Step 1: The Problem

If you or someone you know owns a motorcycle, a scooter, or even a small car, you've probably noticed that it's easy to get stuck in traffic lights. Well, I'm going to explain why it happens, and show you a great little trick that will save time, gas, and frustration, by getting you a green light every time.

Step 2: The Explanation

At most traffic lights and turn signals you'll notice a loop of wire buried in the pavement of the road near the stop line. This is called an "Inductive-Loop Traffic Detector" that operates by sensing a change of frequencies in the electric magnetic field over the coil of wire. In other words, when a car pulls up it senses a vehicle, and the light changes. Though most motorcycles, scooters, bicycles, and small cars don't really have enough conductive material to trigger these loops and change the traffic light.

Step 3: The Trick

Here is the simple scientific trick so you will never get stranded in a traffic light again. I picked up two very strong Neodymium Magnets that have a pulling force of over six pounds each. I also bought a roll of heavy duty exterior mounting tape. After cutting off a small strip of tape, I attached it to the magnets, then I applied it to the bottom of our test scooter. perpendicular to the road, and IT WORKED! These strong magnets produce a very powerful field that increases the inductants in these traffic sensors, and causes the light to change.

Step 4: The Tips

I decided to put the magnets inside a chrome plated pill holder that has a nice rubber "O" ring, so the magnets don't rust.

    U know that the easyist way is to get A world Remote and put in 911 then itll turn green...

    Just wait your turn, how much time are you actually saving?

    @Headlight flashing theorists: Flashing your lights simply makes traffic lights that have motion and light detecting cameras think there are more vehicles waiting in line for the light to change. Greenman, the video's subject nor practice are illegal. It isn't dangerous either.

    This is a neat idea, but dangerous in the extreme as well as criminal in most states. Get caught doing this in a few states and you will get free room and board in the Gray Bar Hotel. Even if you don't get caught, if you cause and accident expect to spend a lot of money in court.

    How and where do you apply these magnets on a car?

    i flashed my brights at one of the the camera sensors (the cameras that senses whos there) and it changed the light. theory is that when you flash your lights the system thinks your an emergency vehicle so it changes for you.

    I think the headlight flashing thing works as they draw more power from the battery, often causing the alternator to run more thus crating a larger electro-magnetic field. Test this thoery out by operating your electric windows as well as the rear window heater instead (obviously not when it's dark and you need your headlights - duh!) as they draw a large amount of power too.

    flashing headlights sometimes works for me. Or trying to go forward/backward couple of feet might help a bit. Of course, do these thing when there is no traffic behind or ahead.
