I've been conducting a study of sorts over the last three months on my effect on streetlights. This fall I noticed that lights were going out frequently just as I passed them or approached them in my car. I think it's always happened, but I just decided to pay attention to it. Since I don't normally get out of work until after 7:30 p.m., I've had a lot of night driving to watch. I've been averaging three to five streetlight shut offs per week, sometimes with more than one in an evening. It's happened on the freeway and on back streets, and in different parts of the Twin Cities. Once in a while, it's the same streetlight but often it's one further down the street or around the corner. Twice it was a stoplight that shut off. I wondered if it could be my car and not me, but then I noticed it happening when I was a passenger in someone else's car. It's even happened a few times when I was out walking the dog. It reminded me of the problems my grandmother has with watches. Any watch that she's worn stops working within a short period of time whether it's a wind up or battery run. The watch just dies. I always thought it must be some sort of magnetic field she's giving off. Do magnetic fields affect streetlights? Could they be hereditary?
