Maybe you missed my reply in the original thread, but I have had success with a red laser:
Almost all public street lights are operated individually by north facing photosensors mounted on top of the light fixture.
Although mine is a bit of a special case, because the north-facing window in the "hat" on top of the light is aimed at a cooperative neighbor's house that is situated uphill from my house, I have been able to turn off the street light across from my house with a red laser pointer for an extended time period. It takes a direct hit to trigger the photosensor, and the cobra-head reflector can block your line of sight into that tiny window unless you have a way of gaining sufficient elevation to aim your laser pointer into the photosensor window.
Another consideration is that you have to leave your laser on it continuously, or the street light comes back on within a minute. I have a Howie Glatter laser pointer holder attached to a spare finder scope that fits on a photo tripod. The finder scope is helpful to aim the red light precisely into the photosensor window. Even then, I have to position my set-up on the flat roof of my neighbor's garage to get a clear view of the photosensor.
Hope that helps,
Hugh Bartlett
