I was visiting with some relatives further out in the suburbs than I happen to reside, and where there are significantly less city lights, particularly in the residential areas. And I considered how much that particular community and others with so few city lights must save on utility costs.
The cons overshadowed the pros, however, as the creepiness of being surrounded by nigh complete darkness settled in, whether or not there was any genuine need for concern, like undetectable criminal activity.
I then thought of how all cities could benefit from motion-detecting lights that would be operable, of course, only when motion is detected, which could save all cities significant utility expenditures.
Motion-detecting lights and cameras that would work simultaneously, in those select areas where the combination would be placed, would translate to well-lit and ultimately safer communities, and all the more if all city lights and cameras utilized this technology.
