It's my understanding that after 2 minutes, if the signal doesn't respond,
you can go ahead [being careful] since the traffic light is
"malfunctioning." [Since it isn't picking up your bike, it's
malfunctioning.]

Quite a few years ago there was a 6-9 month period where they were ticketing
here for running the red. As far as I know they haven't ticketed for a long
time but most loop detectors here will pick up a bike.

I wonder if a magnet of that strength would set a good nail up for the rear
tire?

That's definitely possible.
I screwed up when I jumped in this thread and missed the original post
selling magnets. I'm not endorsing the magnet gizmo in any way and when I
tried to check out the magnet on the link in the post it tried to do some
crazy stuff to my puter. My spam blocker kicked in, my pop-up blocker kicked
in and an install gizmo tried to kick in causing my anti-virus blocker to
kick in.
If you've got a couple old speakers with a magnet of any size it could help
detection without being strong enough to pull junk under your bike.

The problem is an old one. Some road inductor(s) sensors pick up bikes and
some don't. The iron mass is what make the inductance change. I don't
think a magnet [unless is contains a considerable amount of mass] helps
much. I've heard from some riders who use their side stand. The flip it
out over the inductor loop in the street and claim it helps. I don't know.
I know that if I come across a traffic light that doesn't respond in a
resonable amount of time [the law states 2 minutes] then I can presume the
signal is broke and go about my business.
