Traffic Signals are most commonly controlled by electromagnets (also referred to as Inductive Loops), which are buried just under the black lines you see cut into the surface of the road at each lane of controlled intersections - they usually appear as large, black-outlined rectangles in the road.

The moment you pass over an inductive loop controlled traffic sensor with a vehicle that's equipped with a Signal Sorcerer®, the iron-seeking magnetic field WILL detect you and start the light's timer cycle. You WILL get your green light or turn arrow - ABSOLUTELY.

No more waiting for a car or truck to come along and trip the light. No more making right turn and U-turn combinations to get where you're going. Save Gas! Save Time! Save Frustration! Get Your Green Lights with a Signal Sorcerer® Traffic Light Changer!
