There was a youtube video a few years ago claiming you could trigger the light sensor by standing on a metal circle on the intersection, but I think it might have been a prank to sucker people into thinking manhole covers were traffic light sensors.
In my experience, it works with steel bikes - but only if you get the sensor just right.
I had quite a bit of luck doing this with my steel bikes in Mobile, AL - where the streets were pretty run down and you could actually see the sensor through cracks in the pavement.
