“I like the night. Without the dark, we’d never see the stars.” ― Stephenie Meyer, Twilight, night is the best part of a 24-hour day. Cityscapes are lit with a myriad of interesting and colorful light sources, such as lampposts, neon signs, store windows, car lights, and bare bulbs. People dress in their favorite outfits to hangout. Bland scenes by day can suddenly turn ominous and fascinating at night.
The absence of natural light in the urban environment at night has always been a problem. Apart from basic inconvenience, people can’t see where they are going and was easily attacked or mugged over the night. This problem has existed since people began living together, hence, the history of street lights may be longer than we think.
