My own experience with Streetlights has been similar. The last two months or so, when it's night and I go to take a piss (at different times, it doesn't matter), I stare out of the window. Every single time, as I'm looking at the street light across the street out my window, it will go out, or turn on. Every single time. I can look out it from different windows as well, and get the exact same effect.

I've noticed that certain streetlights seem to have a different probability for going off (or on) in my presence. The one outside my window has been 99.99% for the last few months, while some other ones that I pass on the way home from work range from 25 - 75%.

I've always had the "problem", but the past few months the effect seems to have increased greatly. hmmmm.
