Stuck On Red (Traffic Lights)

[Chuck]

Thanks to all for the suggestions. Perhaps a bit of
experimentation is in order. I've never actually observed
any lines or grooves in any of the pavement around here to
indicate the whereabouts of any embedded loops.

There seems to be some doubt as to the effectiveness of the
use of magnets or magnetic force to trigger the signal
lights to trip but I'll give it a shot.

As I already carry a 12volt lawn mower battery for my
lights and other accessaries it should be easy enough to
rig up a pretty powerful electro magnet that I can turn on
an off as needed.

I'll give it a try and see how well it works.

Again,

Thanks and any other thoughts on this matter that have not
already been explored are appreciated.

Chuck
