c.  All parking lot lights, except those required for security as provided herein, shall be extinguished within one (1) hour after the end of business hours and remain extinguished until one (1) hour prior to the commencement of business hours.  For reasons of security, a maximum of thirty percent (30%) of the total lights used for parking lot illumination may remain in operation during such period.
