Large neodymium magnet on the bottom will do it. Most are induction activated. They taught this in every motorcycle driving class I ever attended, along with the rules for legally running a red light.
Well yeah, they have to move over the sensor loop. You can’t just place it in the center. It’s part of a process that happens as, you know, you pull up to the light. They are a little fancy.
Thanks dude, well aware they’re looking for an AC signal. The added magnet isn’t going to influence that, is my point.
Besides limited magnetic permeability of the magnet itself (the thing the loop is looking for), it’s physically not big enough. What you really need is an amplified field distortion, e.g. a field coil which reads the sinusoidal signal being emanated by the sense coil, and loudly plays the inverse back so the sense coil thinks a giant block of steel slid over it.

That way you’ll also automatically collect all sorts of valuable metal treasures along the route. For free!!
At least the screws won’t collect in your tires! Lol
No, it won’t. I invite you to get some large magnets and place them directly on the loop cuts in the street.

This guy inductions.
