Dallas City Council members are set to consider an ordinance Wednesday that would darken thousands of city lights for four hours each night.
According to an ordinance draft, businesses citywide would have to switch off most of their exterior and signage lighting between 2 a.m. and 6 a.m. Violators could face fines of up to two-thousand dollars.
The proposed ordinance is part of an effort to conserve energy and reduce power plant emissions. Other measures to be considered by the council on Wednesday include strict regulations on idling trucks, pollutant-belching vehicles and where the city purchases its cement.
Exemptions in Dallas would include security, hospital, traffic control, residential and transportation lighting. State and federal government facilities, as well as businesses open and operating in those late-night hours, would also be exempt.
Not everyone is enchanted with the idea of Dallas' distinctive skyline going dark.
