beat red lights? thank you science channel

so this might be common knowledge but it was just watching the show Brink on Science HD...and they run this segment on home made inventions...so this dude shows you how to force red lights to change on a motorcycle or small car. Basically the deal is that if your car or bike is too light the sensors below the pavement wont detect it and you can get stuck waiting. However, if you do this you can trigger the sensors....

Trigger Green Lights: Kip Kay: Brink: Science Channel

Trigger green lights!

What You'll Need:
2 Neodymium magnets - Kips uses magnets that have a pulling force of over 6lbs each
Some heavy duty exterior mounting tape
Optional: A waterproof, rust-proof pill holder

Steps:
Cut off a small strip of tape
Tape the magnets together with one side of the tape
Tape the magnets to your to the underside of scooter or motorcycle with the other side of the tape - perpendicular to the direction of travel.
If you desire, you can put the magnets into a waterproof, rust-proof pill holder and then mount the pill holder to your vehicle.

What the heck is going on here:
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.


maybe an old trick but first ive heard of it and pretty badass if u ask me
