As most of us have experienced, sometimes when you pull up to a traffic light with no cars present, it seems like you just sit there and the light won't turn. Then a car pulls up behind you, triggers the light sequence and it finally turns green.

Obviously, this only pertains to lights that have the sensing loop in the pavement. Not a problem with camera trigger lights.

Somewhere I read about a magnetic traffic light trigger. Basically it's a magnet that you attach to the under side of the MC. When you pull up to the traffic light, it's supposed the trip the sensing loop embedded in the pavement so the light will turn green.

Does anybody have one? Does it work?

Safe and happy riding! :action:

Never used one. South Carolina has a new law that allows you to run the light if it doesn't change in 3 minutes.

Go to the local junkyard and get the magnet out of a transmission pan

I had one on my previous bike and only had one light that would not change with it, but it had problems with cars and all there metal. I think mine was the green light something or another and seemed to work. I had a Suzuki Marauder. I haven't had a problem with lights since I got the wing......:waving:

Would an ordinary magnet work? I've got one of those trash magnets from Harbor freight. Could I mount that under the bike?

I read another article about MC riders having trouble with exit gates at parking garages. One of the gate installers recommended; When you pull up to the gate, look at the saw cuts in the pavement and put your wheels directly on the saw cuts instead of being centered in the loop. Should work for traffic lights too...???

Bagmaster, I thought that was two minutes.







I've heard that the magnet does not work too well.

Good point about the cops but they always seem to come out of the bushes every time I take a chance on not being seen. :action:

I had one on my bike. The thing worked well for the first few days. I did some maintenance on the bike and the dang zip ties that was supposed to make sure it didn't fall off were broken and no magnet. Wasn't to much of a magnet if you ask me, it fell off of a perfectly good piece of steel.

Just my own petty little opinion, but if a magnet needs to be zip tied on, it won't have any effect what so ever on those loops in the pavement.

The magnets I used to pull out of klystrons? Now those were magnets. You could NOT pry them loose from a steel plate with a screwdriver, much less just "fall off" from something.

I have a magnet you could pick up a tool box with, laid it right on the seam in the pavement & nothing ............... never had a problem with the Wing, but the Intrude now that's a different beast, never works. ..........:action::action:

Just laying the magnet on the loop won't activate the computer.

Try that same magnet with you sweeping it across the loop.
The movement is what creates the pulse.

But, those loops are actually part of a tuned circuit. They depend on a large mass detuning an oscillator enough to signal the computer something large is sitting in the loop's area.

A magnet per se, I don't think is going to help at all.

John, the one I had on the bike came from the folks at Greenlight Tripper. It had some adhesive as well. I never thought it would work long and it didn't. Some rare earth magnets work very well on the lights though.

Even if the magnet works, it may not make the light turn immediately. It depends on the timing cycle that particular light was programed with. That's why the S.C. law that folks have mentioned is 3 minutes. You have to give the light enough time to go through it's cycle once it senses a vehicle.

And it may have a delay built in before triggering the timing cycle as well. If someone pulls up to the light, stops and then immediately turns right (on red). The delay prevents the light from turning for a car that is present for only a few seconds.

So I am curious, when you put the magnet on the cut in the pavement, did you leave it there for 15-20 seconds? Also, did the light turn within 2 or 3 minutes? Or did it not turn at all?

I wouldn't expect the problem with a wing.........at least the older ones have enough iron in 'em not to be a problem.



My 1100 doesn't have a problem at all....but my plated crf450 will not trip any light in town. It's probablygot a tablespoon of real steel in the entire bike.......



I took the magnets out of a couple of old hard drives and zip tied them under the foot pegs. Problem solved.

I didn't time the magnet but I waited longer than I have to with the Wing to see the crosswalk activate. I had the magnet on a string & lowered it onto the pavement so there was motion involved. I might park at the side of the road some time & try it again by standing there & moving the magnet over the seam when there is no traffic.
