Sec. 28-11. Illumination; flashing signs.
When exposed incandescent lamps are used for ground
signs, marquees, roof signs, billboards or wall signs, they shall
be equipped with gooseneck reflectors or other devices arranged
so as to concentrate the illumination upon the area of
the sign and prevent glare.
Each outline lighting installation and each illuminated sign
shall be controlled by a time switch or externally operable
switch which will open all ungrounded conductors and shall
be suitable for conditions of installation, such as exposure to
the weather.
Any existing flashing sign, except those listed in subsection
(3), of section 28-9, shall be turned off by 11:00 P.M. every
night. (8-5-63.)
