On a recent club ride I heard about using the "Green Light Trigger" device to trip inductive coil
traffic light sensors. This product is manufactured for motorcycles. Any in the group have
experience using the GLT or have any other ideas for triggering traffic signals when no autobeast
is present? I've called around the cycle shops in Sacramento and the GLT is not available locally.

Lon,

I have one mounted on my GRR and as far as I can tell my old method of muttering, "Change, dammit!"
works just as well.

"when there are no autobeasts around" I run the light. I have even stopped using the pedestrian
button most times. When I push the button it really ties up traffic since the signal then holds for
a "virtual" pedestrian and I am usually two blocks away before it changes again.

In other words, In my experience, the lights that I couldn't trigger without the GLT won't trigger
with the GLT.

It is your obligation to do so when you can safely. The light that does not trip for your vehicle is
defective. Treat it as you would any other defective light. You also have an obligation to report
the defective light.

Texas Code: Sec. 551.101. Rights and Duties

(a) A person operating a bicycle has the rights and duties applicable to a driver operating a
vehicle...

You have a right to a working green light.

In Pennsylvania, all DOT-approved coil-controlled traffic lights must sense bicycles. The rule here
is: if it doesn't change for you, treat it as a stop sign and proceed only after stopping and
determining that the intersection is safe.

One note about pedestrian crosswalk buttons: many neighborhoods are now installing these to turn ALL
lights red and then signal pedestrians with a "walk" sign. Take note to that if you plan to push
that button - you won't get a green light and will have to act like a ped.

I have had a Green Light Trigger mounted to the bottom frame of my VTX (that's a motorcycle for you
bicycle-only guys) for about six months now. It has absolutely "cured" two stubborn lights on my
regular route. There are a few catches, however:

The GLT must be close to the ground to be effective - I don't recall the recommended maximum
distance to ground, but 6" (or closer) is ideal. Also, the "signal" is generated by the motion of
the GLT passing over the sensor coil (which is below the road surface). The instructions recommend
rolling over the sensor at 6 to 8 mph. While it's no problem to do this on most motorcycles (and
still brake safely before the intersection), it may be more difficult on a bicycle.

I have a big powerful magnet I took off of an old woofer. I use it to find small parts I drop in the
grass. It is kinda heavy, and I'll hafta think up a way to mount it on my R40. The field may be
oriented the wrong way too. But maybe....

And puleeeze don't tell me to work on concrete of put a cloth down. If I wuz capable of learning
that simple bit of wizdom I wudda larned it a long time ago.

The coil type switches can usually be triggered by a magnet. Go to wondermagnet.com and get some
nice strong neos. Hook one to the bottom of your frame and it might do the trick for you. If it
doesn't work, you still have a very nice, very strong magnet to use somewhere else.

A more unscrupulous method I've seen used is to take advantage of the emergency vehicle sensors. The
older style operates by detecting flashing lights and usually have the sensor mounted above the
lights on the light pole. People have made the lights change by flashing their headlights or
flashing a bright flashlight at the sensor. As these were prone to abuse, the newer emergency
vehicle light controllers are operated by radio from small transmitters mounted in the emergency
vehicles but there might still be light sensors around where you live.

But don't ride with your creditcards anywhere near it. ;-)

Nope. 🙂 I used some neos when I built my windmill and they are crazy strong, even dangerous strong.
I pinched off a fair piece of my finger when I wasn't paying attention and brought them too close
together and they were only 1.25" x 3/8" disks.

A neo might tend to pick up lots of fine pieces off the road too. Might even be a small public
service to do a magnetic sweep of the areas we ride?

I just had idle thought. Would it be possible to make an electromagnet running off a lightweight
battery that could be triggered only when crossing into the sensor zone. I would think it could be
pretty powerful and light weight. Thoughts?

Traffic detectors use 'induction' and 'changes in resonant frequency' and NOT magnetism. Poor
'magnetism', the only invisible force y'all can feel so it is used by health quacks and now traffic
engineer quacks.

An inductor is about as simple as an electronic component can get -- it is simply a coil of wire. It
turns out, however, that a coil of wire can do some very interesting things because of the magnetic
properties of a coil.

Putting iron in the core of an inductor gives it much more inductance than air or any non-magnetic
core would.

The inductance will be much larger because of the large steel object positioned in the loop's
magnetic field. The car parked over the coil is acting like the core of the inductor, and its
presence changes the inductance of the coil. Most traffic light sensors use the loop in this way.
The sensor constantly tests the inductance of the loop in the road, and when the inductance rises it
knows there is a car waiting!

What!! No magnets? Charlatan!

I wonder how many here would choke (pun) on saturable current potential transformers? Or that before
transistors they were common control interfaces and still are in high current applications.

Thanks for being a voice of reason.
