I saw a bit on TV regarding the inductive loops that control most stop lights. As you know most of the time a scooter does not trigger these to change the light. There are some lights I just avoid for that reason. Sometimes I just have to turn right because the light will not change.
The TV show suggested adding two very strong magnets near the bottom of the frame and a ring of copper wire around the wheel rim. It worked.
I am skeptical...

There have been a couple of members here who tried the magnets, with mixed results. I always try to pull up enough so that any cars behind me can inch up and get their metal over the sensor.
In Vegas, they are slowly changing over to cameras, and those intersections do seem to work well. They also recently passed a law here stating if the light doesn't change through two full cycles, you have the right to proceed when it is safe to do so.

I did an online search. One idea is an old speaker magnet attached to the bottom of the frame. The commercial products don't have good reviews. Magnets, being ferrous, will rust, and cause your frame to rust. Not so good.
I also found out in California if a stop light is not operating, you can treat it as a 4 way stop. That is at least two cycles of lights without your scooter being sensed by the loop or camera.
A motorcycle cop says, for the camera systems, it is best to weave slightly so the camera operated devices can see your movement. Also flashing your lights 50 yards back will trigger the camera systems at night.
One guy put a magnet in the heel of his boot and he steps on the loop......
Most of it looks like JuJu.
Staying to the side of the loop where it connects sends the strongest signal according to the traffic engineer web sites.
It also appears as many as 25% just don't work at all.... Always have an alternate plan.

nearly every road around here has a median so i usually do a michigan left. even if the light is triggered it's usually faster to go straight if light is green or turn right if it just turned red and then do a U-turn.

Giving the bike a little throttle will increase the ignition pulse enough to trigger some lights while the pressure pad ones may never trigger with a bike that weighs less than 400 lbs.. On those that don't trigger most juristrictions will after 2 missed cycles have you to treat the light as a 4 way stop and allow you to proceed with caution.

If you call your DMV they'll usually adjust the ones you sit at most often. Best if you're willing to meet them there so they can test it with your bike. I haven't needed to call, but my MSF coach did on several area lights. Said those now respond to a bike same as a car.
I did call our roads guy about a poorly-finished road repair. They hadn't filled the edges to be flush with the rest of the street. I hadn't driven my scoot over it but could tell from the feel with my car's tires that it wouldn't be pretty on the bike. He had it fixed the next day.
My coach said anyone he's ever dealt with about things like this are very willing to work with you. They don't want unsafe situations that might result in accidents.

The best trick I found is to go talk to the city engineer.

They do work. Go on Ebay and look for "rare earth magnet" and buy biggest one you want to spend money on and mount it as low as you can on the scooter.
We have a law in Minnesota that allows you to wait for a reasonable time, check to make sure it is safe, and then go through a red light if you can't trip the light on a cycle. I use it a lot at a particular intersection where there is no traffic but I can't get the light to change if I wait a century. We just adopted that staute a couple years ago but many states have it.

Sometimes a old hard drive magnet hanging under the belly pan of the bike can help too. Any computer store would probably give you an olddrive magnet and for very little to nothing at all.

What I do is when I come up on an intersection, I move up passed the white line and let the car behind it the mark

This will solve all of your problems. When it is safe for you to go, just go. You're not going to get in trouble. I do the same in my car. If there is absolutely no one coming through the intersection, I go. I once got pulled over at 3am for doing this. The cop didn't care about the light. He wanted to see if I was drunk. he said why did you go? I said there were no cars at all and I didn't see any reason to sit there any longer. Have a good day sir.

I have used the magnet method with mixed results. It helped with some stop lights but not others. I found that with some lights the city engineer had set it for trucks to discourage cars from using it as a short cut through the industrial park. They wouldn't change that one then. But others they did and some were set on a cycle as the loop in the road was broken.
Now I used a fairly large and strong neodymium magnet, something like 4 inches long and a 1/2 thick and a inch or so wide. It actually attracted some screws and nails to it when I was riding around. So it helped to prevent possible flats too. It was attached onto the frame underneath on the cross brace near the center stand. One thing is that it was near the oil drain plug, so one had to watch it with the wrench as it has the tendency to snatch the wrench out of your hand if you weren't paying attention. So it was a fairly strong magnet and it would hold onto things tenaciously.
But around here now, they are starting to put in the video detection systems where a computer uses a video camera to determine when to switch the stop lights. Those pretty much alleviate needing a magnet. But I figured, what the heck, it can't really hurt anything, so I used a strong magnet.

In SC the magnets do not work at we use weight sensors . I bought a Green Light Trigger which is a magnet that you hang underneath the body . I try to pull up real far and have a car behind me move up closer to me in order to trip the sensors at certain places . In SC if you are on two wheels , after a two minute wait and if it is clear , you can legally run through a red light . I have seen cars follow me but they are not included in this legal loop . Some times I stop just before a redlight and let a car get pole position when traffic is heavy .
