Default Red lights late at night and weight sensors wont trip, what do you do?

Hopefully this will help some of you with this problem.

Run the ****er
Wait for a cager to pull up behind you
Sit there like a tard till you run out of gas
Rock back and forth trying to get it to trip


Underneath the pavement there is an inductive-loop traffic detector. This loop detects the amount of iron inside the loop. The problem is that most motorcycles contain more aluminum alloys and fiberglass than iron.

There are devices that you hang from the bottom of your bike that can help with this. All they really are are neodymium magnets that fool the signal into thinking that there is a larger metal object in the loop. The magnets inside an old computer hard drive are neodymium magnets. You could salvage some from an old hard drive and attach them to the bottom of your bike, as low as possible.

Another thing to try is to stop near the edge of the loop. You can tell the edge of the loop by the saw cuts in the pavement. Turn off the engine and re-start the bike. The magnetic signal generated from the starter can be enough to trigger the sensor.

You could also try stopping near the edge of the loop. Put the side stand down. The metal side stand near the loop may be enough to trigger the signal.

Not all cities have "demand-actuated" traffic signals. Do not expect this to work at all times. If it is not a "demand-actuated" traffic signal and you run the red light, you could set yourself up for a hefty fine.

Someone did a test of all the theories you just posted + some others.
all of them FAILED

If you get to a light and it wont turn, either make a right turn, or look both ways and ride though the light. I've gone through many relights on my motorcycle. Sometimes you have no choice, its one thing to run a redlight, its another to look both ways and enter the intersection only when there's way more room then needed. Most of the time I wait til theres a big break in traffic so there's zero chance of any car driver freaking out. I've yet to get a ticket. I also asked a handful of local county police what their view on it is and they've told me as long as its clear that I'm not just blowing through the light they dont care. Again, there's a difference in going to a light, stopping like a stop sign and riding though it, it's another thing to stop and wait 2 minutes go mofo! then processed with care.

Thanks for the correction. I thought it was pretty interesting either way. I haven't had a chance to try it out though and won't waste my time now from what you've said. I always get stuck at this light and it's really awkward at midnight just chilling for 3 midnight at a light that won't turn...

I just ride through them. I make sure nothing else is coming first. I've been stopped once, but the Officer was nice enough to explain he knows all about this problem and he feels the pain, and he left me go with nothing.

Yeah, Correct answer is stop and proceed with care. Havent been stopped on a motorcycle for this, but in my Z.

A light near my house would take five minutes to change. i got caught running it after I had stopped for ten seconds.

I politely explained the situation to the cop and he let me go!

Even though red light chargers are highly illegal, what you can do is attach a few strong magnets to the bottom of your bike to trip the sensors. It's a magnetic pull, and not based on weight. The magnets change the polarity just enough to sense you're there.

question is what do you do if you are in that situation if you have some alcohol in your blood/on your breath. Just hypothetically speaking of course

Wasn't that listed in the first post? it's also nothing more then "talk" it doesn't work the way we would like it to.

In other words, it works but you need such a powerful and heavy magnet to get it to work they worried about if it throws off the internal workings of the motor.

In other words it was like 10+lbs worth of magnets to get it to trigger anything. A better option is to not ride sport bikes. go to a full blown cruiser like a Ultra Classic and the weight will manage to trip the light.

In NC they made it legal for bikes to run the red lights in these cases last year. If I remember right there are a number of other states who have done the same recently or are planning to so check your state laws....you may not be risking a ticket after all......
I'd still do it, when getting pulled over I would ask as polite as I could, what should I have done? I've been sitting for 3 minutes with all of 4 cars to drive by and it has yet to change.

It's like when a normal traffic light gets stuck on green. I've had it happen a handful of times when in my car, traffic backs up down the road, next thing you know people start running the light 1 by 1. Should they all get a ticket?

I've seen a light get stuck on red after a power outage. Only thing was it's almost impossible to make that intersection under those situations. Eventually, people started peeling off in different directions and find a way around. I imagine it would be very annoying on a motorcycle.

Hopefully it's not more than few drinks. DUI/DWI people get off easy than what they deserve IMO. At any rate, not get caught.

Almost all the lights here(TX) have light-sensors, not magnets, so a quick flash of the highbeams 1/4mi back trips them. Otherwise state law says after 1 redlight cycle and no traffic, if deemed "safe", you may run the light to make your turn.

It's a little project box from radio shack with neodymium rare earth magnets glued in it. That's why "for stronger effect install two".

I should start making and selling them. Buy the neodymiums in bulk, resin them into a box, stick it in a bag with a zip tie, print some labels on thick paper and make a killin in the spring on eBay.

Without seeing a legit review of it from a motorcycle mag or website, that item is no more useful to me then a 20c resistor used to gain 40WHP when added to a factory ECU.

It WORKS jeffie. It's just magnets inside a box. BTW, aren't the majority of lights activated by headlights?
