Ever wonder what makes a traffic light turn green? Some people think it's timing; others are sure there are weight sensors in the road. Still others claim it's some sort of camera system. But actually, it's magnetic field detectors: coils in the road detect large metallic masses over a plate by the stop line, and the traffic light begins its cycle. No cross traffic, no need for a light change. Slick, eh? Except if you ride a bike. See, those carbon and aluminum frames are great for speed and lightweight...but not for telling magnetic sensors you are there. Result? Every morning, I face the ethical dilemma of either waiting for a car to pull up to a certain light so I can turn left...or run the light. Guess what wins most days? However, my lawbreaking may be at an end. The Green Light Trigger pumps out a strong enough field to fool those sensors into believing my Fuji Robauix is a Ford F-150.
