Although I agree with Paul and Jason, I think Jason is more on the money, after Sun Set is only a green concept to energy saving and rightly so, but it has no value at all to astronomers, and/or imagers.
Why could they not be set on auto, (all street lights that is) and half switch off after midnight, how simple is that,
we don't need all those lights burning during the night when most are in bed,
except us of coarse.
