I always thought that those markings in the road where to sense a cars weight and then trigger the light to change....
Lines are there to sense a change in the magnet field..A lot of times bikes dont trigger them.
When i come up to one of these lights ,i park directly on one of the lines.Its a 95% chance that the light changes for me..Cost =zero..

the brand most carry are called "signal wizard" and they look EXACTLY the same as the vid.. i had one on my last bike they are only 19.99 and triped the light about 75% of the time. good investment
I have serious doubts whether 2 sq.m. inductive loops can be triggered by 2" magnets... your spark plugs and metal parts cause way more interference electromagnetically than could a small magnet. Instead I'm +1 for stopping right over one of the lines.
Here's a simple test... WALK over to one of the signals with a magnet in hand. This will be a good test whether the magnet triggers anything (assuming you're not part android). PLEEEEASE do this test and post the result someone! Hold the magnet a couple of inches from the ground (maybe tape it to the top of your shoe and walk into and around the loop?).
