The traffic light near my house out of a dead end street where I need to make a left ALWAYS failed to notice my bike. To make matters worse, there's a city park near by and cops always hang out there in the AM when I leave for work.
I tried everything. I did the starter trick. No deal. I put a mondo magnet on the tab used for the center stand. Nothing.
Eventually, I began to do stop and go's figuring WTF? After a short stop, I'd just gently pull away short-shifting up the street so I wouldn't create too big a ruckus.
If I was pulled over (I never was), I had the story all worked out. I'd even point out the rare-earth magnet I was using to get noticed.
My son's Mustang even failed to trigger it at times. He works in law enforcement and I asked him to look into it. He filed official complaints and eventually they dug up the box nearby and remedied the situation.
I've kept the magnet where it was, but I'm not sure if it makes a difference.
I plan to die young, as late as possible.
