Hey All,

I am considering buying one of those little boxes (magnets), that hook to the bottom of your bike to help change red lights to green (As compared to sitting at a red light forever), but am curious if anyone owns one or knows if they work???

Thanks,

Carl

Assuming the polarity of the magnetic field generated by the magnets is in phase with the loop detector's tuned frequency and the subtended angle of your position is within the vector parameters of the loop's influence, it might work.

Thank you for clearing that up Dr. Spock. :confused:

In my area, they have chaned them all to motions sensors mounted on the light poles. They look like cameras, but they are not.

Usually the ground loop senses the metal of the vehicle as it passes over. Motorcycles present a problem with this because it doesn't have the same mass as a car/truck. In Missouri, a law was passed a year or 2 ago that allows motorcycles to make a left against a red after a reasonable wait...if you dare.

Work as good as deer alerts
Don't knock the deer alerts. I had 3 roo alerts on my bike. 1/ The first one was for the roos that could hear. 2/ The second one was for the deaf roos. 3/ The third one was for all the deaf old buggers who thought that they could stand around and say what did you say. Psychologically it is good for me. Eric

Well, here goes the cheap skate in me again. I know they want $30 to $70 for those magnets. Go to Harbor Freight and get a Welding magnet for about $5. Used by welders to stick to a metal post and hook the neg lead of the welder to it. Has a bolt and nut on the top side and could easily be put on a belly pan. Whether they work or not, I don't know but 2 days ago I would have given you $50 for one cause I was trapped at a light till a cager finally pulled up behind me and tripped the sensor.

Read some research that basically said they don't work.

I sat in on a Riders Ed. Class a couple years ago put on by a woman that worked for the D.O.T. What she said was to look for those circles or boxes in the road surface and be sure to ride through the center and possibly stop over it. If you ride to the side, it more then likely will not detect you. Seems to work here in the Northwest.

That's what I was saying. Put yourself in a good position.
I think I know what you are saying is: The numerical product of the length of two vectors and the cosine of the angle between them, which is completely specified by a magnitude and a direction that guides by a means according to vector. Eric

It is truly a great moment when two great minds discover each other.

Testicals deviant three to fuds law: If you push something hard enough, it will fall over.

Just make sure you stop on the little square or circle in the asphalt.... what ever is there.
