If you want to turn off the light before your show runs, You can get one of those stake spotlights from walmart and aim it at the streetlight's photo-sensor.
It shouldn't take more than a second or two to turn the light off. Just add it in your sequences as maybe an output from a ssr, or LE. then keep an eye on it to see when it returns (timing) and trigger another burst of light at it during the show. Once the show is done, the light will still come back on.
(I think they have a 5min wait before turning back on. So maybe a burst between songs.)
