Introduction: Trigger GREEN Traffic Lights
Step 1: The Problem...
At most traffic lights and turn signals, you will 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 in frequency to the electromagnetic field over the coil of wire. In other words, when a car pulls up, it senses the vehicle and the light changes. Most motorcycles, scooters, bicycles and small cars don't have enough conductive material to trigger these loops and change the traffic light.
Step 2: The Solution...
Produce a very powerful field that increases the inductance in these traffic sensors, and causes the light to change! Here's how to do it...
Step 3: What You Need!
2 Neodymium magnets. I chose two from CMS Magnetics that have a pulling force of over 6lbs each. I also bought a roll of heavy duty exterior mounting tape.
Step 4: Attach It...
After cutting off a small strip of tape, I attached it the magnets. Then I applied it to the bottom of our test scooter, perpendicular to the road.
