There once was a street light near where I lived that I discovered I could magically "turn off" whenever I went near it. I quickly discovered that it wasn't the case at all.
Apparently, when a sodium street light "bulb" (the most common type) is reaching the end of its life, it cycles on and off in a definite and repeating pattern.
See this Guardian article for more details on this.
It may be the case that dear Marcus has unconsciously got into a rhythm with the street lights on-off cycle.
It's also likely that, in any large group of street lights (such as on a college campus or gated community), that several street lights are in need of new bulbs, hence Mr Tisdales assertion that there are only certain street lights that he can affect; quote "
just a block away from my gated community, on a designated test circuit determined by me."
This says, to me, that there are a few broken street lights near his community and that, unconsciously, he "knows" (or even consciously and has timed them) which street lights are going to respond to his proximity.
Therefore, any test should involve, as per his instructions, a circuit as designated by him, but that circuit to be provided in advance, so as to allow the bulbs in the street lights to be tested and replaced if required.
