Why do skyscrapers leave lights on at night?
Since not all workers leave at the same time, no one will be left in the dark if the lights remain on as the other workers leave the room.

The FCC has been given the authority by Congress to require the painting and/or illumination of antenna towers when it determines that such towers may otherwise constitute a menace to air navigation. 47 U.S.C. § 303(q).
What are the requirements for an antenna tower?
