Bikes & Intersections--Signal Trigger Products

Coolmaker and I both have these on our bikes and they make a huge difference. It is a strong magnet that mounts on the bottom of your bike, so when you come up to a stop light the magnet trips the sensors (cut lines in road) to make the light turn green. I have seen times that I just pulled up to the light , and in a few seconds the light tripped for me. I bought the original one before the High Powered one came out. Well worth the money in my opinion!

I was pleasantly surprised at how good these things work. If you line up the magnet with the strip in the road as you come up to a light, it will trip it pretty quickly.... :wink:

Globe and Mail Update

Motorcyclists often complain that drivers fail to notice them and cut them off and make other dangerous moves that threaten their safety. Bikers also have a problem with traffic lights that fail to notice them. The bike is too light to trip the sensors that change traffic lights, so riders have to sit for long periods of time, with no other traffic in sight, until the signal goes through its regular complete cycle.

Most traffic lights in North America are controlled by a system that not only has a regular cycle, but also a sensor system that detects the presence of vehicles and changes the cycle accordingly. They are commonly used in situations where a secondary road intersects with a primary route or where a left turn lane is in place. The normal signal cycle favours the primary route with longer green light cycles for that direction interrupted occasionally by a brief green for the secondary route. In cases where a left turn lane is in place, it will activate that arrow when there is traffic in that lane.

To allow the signal to change in response to the arrival of vehicles on the secondary route or left-turn lane, magnetic induction loops are buried in the pavement near the intersection. When a vehicle arrives, these loops detect its presence and tell the system a vehicle is waiting in that lane. The theory is simple and effective — unless you are aboard a motorcycle or in a small light vehicle. The problem is that the sensors are designed to recognize great big hunks of metal, like cars, trucks and buses and cast-iron engines. Unless there is enough iron or steel to trigger the magnetic loop, it does not send a signal to the control box. This is commonly the case with motorcycles and increasingly with small cars with aluminum engine blocks and lots of plastic.

Unless another vehicle with more steel comes on the scene behind you, the signal will continue to operate on the cycle that heavily favours the main route — unless you have a Signal Sorcerer installed on your vehicle.

This extremely simple, small $25 device was originally intended for motorcycles but works just as well in a car. It consists of a strong magnet encased in weatherproof plastic.

Attach it to the bottom of a vehicle — bike or car — using the built-in double-sided tape and tie-wrap and you're in business.

The magnetic field it produces is strong enough to register your arrival at the intersection. Rather than wait for the full cycle, the system will revert to a shorter one, giving you a green light much sooner than it would have otherwise.

It has become common practice in many municipalities to equip emergency response and mass transit vehicles with devices that use infrared or radio signals to change the light. The Signal Sorcerer won't do that, which would be illegal. But it does level the playing field by announcing the presence of lighter vehicles at the intersection, allowing the traffic control system to operate as designed.

I bought two of these things and they do indeed work. I put one on my bike and one on Squirrel's. If you line the magnet up with the slice in the road, it will trip the light real quick. Worth the money many times over.. :wink:

And you will pick up any loose screws or nails along the way.... :lol:
