Press the starter button. 
If you're on a motorcycle you can pull in the clutch, stop the engine, and press the engine starter button. The starter is powered by an electromagnetic motor, creating more magnetic energy and tripping the sensor.

It's important to remember to try and get your motor right on top of the line that marks where the sensor is, not in the middle of the circle or the square that the line creates. The wire pickup that senses a vehicle is actually under the line you see, so if your motor is in the middle, the sensor has a tougher time sensing you. Does that make any sense?
I suspect it may be true. I seem to have better luck off to one side or the other, never trigger it while in the middle.

I know a guy (doesn't ride) who lines his boots with magnets because he thinks it makes his feet feel better. He also has a vest with magnets sewn all through it because he claims it cures his back aches. If I can talk him into taking a ride on the back of my bike, we'll test it.
I wonder if he would trigger the sensor if he laid on the ground in the middle of the sensor and rolled around?

Wow! I usually shut-off my engine - walk over and push the walking button! Maybe the light changed because I was restarting my engine!

beat me to it.
a cop once ticketed me for "running a red light", after I sat at that thing for 4 light cycles (almost 16 minutes), got tired of waiting, and just went when it was clear.
he even said he was watching me, waiting for me to run it. I asked "well, what are we SUPPOSED to do"? and he actually answered "go another way"
that did it, I looked up that very CVC section, and videotaped an hour of that light, including 30 minutes of me sitting at it, trying to get it to trigger green.
then I took the cop to court, and the judge dismissed it after seeing the tape.
the magnet thing, like the kickstand/starter trick only works on SOME lights,...and on some other lights it seems like nothing on a motorcycle will ever trigger it.
anyone carrying a 2lb block of steel around?

My HD XL has no problem either.
See above. Hahahahaharley
No effect. Other than you are now ball-less.
Yup. If a sensor is poorly adjusted, not much is gonna help.

I recieved a ticket for the same thing and the C.H.P said the same thing "I watched you" good for you ReckonI just paid my ticket figuring it would be my word against a LEO and id loose.

Nah, as far as I know its just volume. We can check and see how many cars turn at at an intersection or how many cars go through at a given time interval.

Circle Jerk in the Sink.
Just had this happen to me at an intersection in Livermore. In my cage stuck for 6 cycles of the light for like 10 minutes... I was in the lane going strait and had people in left and right turn lanes next to me so no way of cutting them off...so i proceeded through the red light on my "turn". Then i realized..great its a red light camera intersection...so I'm preparing to fight this one in court. I even called the non-functioning light into the city and will use that and the CVC if i get a ticket

Use your side stand
Most of the time I can trigger a light signal by lowering my Side Stand (if you don't have a kill switch on it), then blip the motor once or twice.
If the sensor is magnetic, that will, usually get the light to recognize you.
If you have a kill switch wired in to your gear selector, it might be more involved, like putting it in neutral, then lowering the stand and so on.

Stationary (!) magnets will have *no* impact on the frequency the sensor loop is resonating with.
Stopping directly on the sensor loop wire will bring conductive material (aluminum, metal, etc.) close to the resonating field and hence change the frequency. This will in turn trigger the required effect - green traffic light.
The rim of the tires, the side stand or a metal boot will help.
However, the sensor has to be adjusted to accept non-cage interference. So it might or might not work - which brings us back to snake oil...

I dunno, usually I do okay waiting the couple of light changes and sneaking through. One time in SF, though, the cross traffic was way too heavy, so I finally put down the kickstand, dismounted and ran over and hit the pedestrian
What the Hell did he do?

My gf's aunt is into that stuff, too. Multi-level marketing BS. Did someone mention snake oil?
tip I got that seems to work fine has more to do with the speed in which you roll over whateverthefucktheygotburieddownthere....if I'm first in to one of these 'problem lights' I just try to roll it over real sloooowww...seems to give it what it needs and I'm good to go in one light cycle, sometimes less.

I heard that standing naked on the loop, throwing a dead cat over your back at full moon also triggers the green light... 
"The electronics unit transmits energy into the wire loops at frequencies between 10 kHz to 200 kHz, depending on the model. The inductive-loop system behaves as a tuned electrical circuit in which the loop wire and lead-in cable are the inductive elements. When a vehicle passes over the loop or is stopped within the loop, the vehicle induces eddy currents in the wire loops, which decrease their inductance. The decreased inductance actuates the electronics unit output relay or solid-state optically isolated output, which sends a pulse to the controller signifying the passage or presence of a vehicle.
Vehicles passing over or stopped within the detection area of an inductive-loop detector decrease the inductance of the loop. The electronics unit senses this event as a decrease in frequency and sends a pulse to the controller signifying the passage or presence of a vehicle."
[...]
"The ferromagnetic effect increases loop inductance. However, vehicle-induced eddy currents decrease loop inductance even more. Therefore, net effect is decreased loop inductance when a vehicle passes through the detection zone of an inductive loop."
(http://www.tfhrc.gov/its/pubs/06108/02.htm#theory)
How the hell is a little magnet supposed to lower loop inductance?
The only thing that matters is to bring the motorcycle/metal as close to the loop wire as possible.
Bottom line: Yes, we need more snake oil!

I wonder what duration change is necessary. Seems that placing a strong enough magnet so that its field is parallel with the loop's field and then reversing the magnet's field would increase and then decrease the field of the loop. If the duration required to trigger it is only momentary it would work.
My first stoplight from home doesn't respond to me so I may go try this out.
