Those rectangles sense when a car is above them because the whole car is somewhat magnetic. Its just a coil of wire and when you drive over it it produces a very small ammount of current. A magnet would do the same thing but i doubt from a mile away.

Re:I hate red lights, do you?
Out here they use the magnet deals and timed cycles. That ---- pisses me off late at night. I can hit every single mother ------- red light and it turns green for NOBODY. Nobody is coming, yet it turns red for me and green for nobody. OMG I want to shoot people when that ---- happens.

**edited for Doc.boost**
Those who think that product will work are all wrong.Street lights work with magnetic loops under the pavement that sense when a car is at an intersection.That is then relayed to the controller wich has a timer.
That ---- he's selling wont work.
What sets off the signals to turn green for emergency vehicles is a sensor on top of the light that looks like a little camera.Its light sensative.you need the intensity of a flashing strobe light at a specific distance to set it off so that the light turns green for you.....just be patient
.
Its just like when dumb ----------ers that think that the faster you push the button to cross the street the faster it will turn to let you cross.....its a ------- switch!You only need to push it once.You can stand there and push the button till your fingers fall of and it wont turn anny faster.
How the ---- do I know all this.Well Ive been an electrician long enough

Re:I hate red lights, do you?
streetlights work in one of two ways, most operate of time based sequence and others work of the presence of vehicles.
some work via time base during the day (peak hours) then switch to presence base at night time. next time u drive late night/ early morn, you will notice how the light changes as soon as you approach it. this is trigered by magnetic sensors in the ground like some one else sed. next time you stop at a light look on the ground right before the intersection, you will see what looks like boxes with the edges cut off, thoes are the sensors.
also the magnetic thing for motorcycles will not make the light turn green as you approach it, it only lets the light know that you are there so, it will put you in que and not make you sit there for ever.
the other device is basically a strobe light that flashes at a high rate of speed, letting the light know that an emergency vehicle is there that neeeds to get through. if u look at newer stop lights, they have mounted on top what looks like a camera on top that seems to facing the wrong direction. that is a flood light that is designed to let the emergency vehicle know that the light has cahnged and its safe to proceed.
btw, my unlce works for florida DOT, thats how i know this.
