Okay....this subject was discussed in another topic. Don't remember where. Anyway....
I know the problem well, as I've sat at busy intersections with cars waiting behind me, and I've gone so far as to wave for the cars to pull up over the roadway sensor wire behind me....and I have just run the light a few times, too.
First, the green light trigger is a magnet. Yep. And it is fastened under the bike, too. It is one of those things that I wish that I had dreamed up, because people will buy them and I'd be laughing all the way to the bank
Of course, people won't buy more than one when they find out it doesn't really help....but if you sell just one to every biker...hmmm. Eventually it will go the way of the pet rock.
Second, a magnet will not effect the bike's ignition system...unless it is a good bit more powerful. But in that case, you'd be pulling man hole covers out of the street... Don't worry about that....
Third, here is the real truth....for when you get to the point that you want to run the red light. The wire in the roadway is part of a sensor that uses an electrical property called the "Hall Effect" (if my old mind remembers correctly). What that means is this....there is electrial current in that buried wire and when current flows it creates a magnetic field in that area. Then when something electrically conductive passes through this magnetic field, the magnetic field strength is changed which also effects the current flow in the wire. This change in current flow (though really small) is detected by transistorized devices in a box somewhere which in turn triggers the traffic light change....but a motorcycle doesn't always have enough mass to create enough change. So what can you do?
Try this....Grab the kill switch! Kill the engine and restart the bike. Yep. As the starter runs, the electrical current from the battery, starter relay, and starter motor will create your very own magnetic "pulse".... and your magnetic pulse will interrupt and effect the roadway sensor. Works most of the time...
....and, of course, for those few moments that nothing seems to work....look both ways, and run that darned light. As they say, "it is often easier to ask for forgiveness, then to ask for permission"
