Red light traffic light changer mod

ACCESSORY 43: Red light traffic light changer $0 @ Reused junk

It's not what you think.

Although ambulances and police cars do have devices in them that literally change traffic lights from red to green in seconds to allow them to pass more safely through intersections during emergencies, this isn't what I'm going for. Having something like that in a non-city or government vehicle is punishable by fines and imprisonment.

Not worth it.

The device I'm looking for is to solve one problem. Small vehicles like bicycles, motorcycles, mopeds and tricycles are not detected at intersections where traffic lights change by under ground sensors. Our tiny vehicles are too small and the amount of metal in them doesn't trigger the traffic lights to turn green appropriately they effectively do for cars - a much larger mass.

Solution? Magnets. A company called Green Light Trigger sells magnets for $25. To keep $25 in my pocket, I looked for other sources.

Hidden inside computer hard drives are such neodymium (ultra strong) magnets. After watching some Youtube videos on where they are located and how to disassemble them, I took one apart from an old '80's computer and will be attaching it to the trike shortly.

This is how they look like. My old drive has four tiny ones. A newer drive from closer to the millennium will have two large ones equal to two of these.

Although I haven't personally encountered traffic lights not being able to sense the trike, I can imagine how frustrating it would be if I ever were to encounter such an intersection where the pedestrian button wasn't conveniently located or existing. As soon as I figure a nice clean place to put this, I'll pop it on and hopefully I'll never have to experience this traffic light issue. I'm tempted to put it on the bottom of the frame for maximum effectiveness, but I'm worried if and when I need to jump a curb, it'll scrape right off.
