(4) No sign may be painted onto the roof of a building, and no flat attached sign is permitted on the roof of a building.
(5) No illuminated sign that has an effective area of 400 square feet or less may have a luminance greater than 300 footlamberts, nor may any such sign have a luminance greater than 300 footlamberts for any portion of the sign within a circle two feet in diameter. No illuminated sign which has an effective area greater than 400 square feet may have a luminance greater than 200 footlamberts, nor may any such sign have a luminance greater than 200 footlamberts for any portion of the sign within a circle of two feet in diameter. The measurements of luminance are taken from any other premise or from any public right-of-way other than an alley. This subsection does not apply to signs authorized by Subsections 51A-7.1727(c), (d) or (i).
(6) No illuminated sign, nor any illuminated element of any sign, may turn on or off, or change its brightness, if:

(B) the change of message or picture occurs more often than once each three seconds for those portions of a sign which convey time or temperature, or once each 20 seconds for all other portions of a sign; or
(C) a portion of the sign, within a circle of two feet in diameter, has a luminance greater than 200 footlamberts when all elements of the sign are fully and steadily illuminated.
This subsection does not apply to signs authorized by Subsections 51A-7.1727(c), (d) or (i).
(7) No sign or any part of any sign may move or rotate at a rate more often than once each 10 seconds, or change its message at a rate more often than once each 20 seconds, with the exception of wind devices, the motion of which is not restricted. This subsection does not apply to signs authorized by Subsections 51A-7.1727(c), (d) or (i) , unless the sign is visible from the main traveled way of an expressway.
(8) No sign may move, rotate, or change its message at any rate if any of its elements or any illuminated portion within a two-foot circle has a luminance greater than 200 footlamberts. This subsection does not apply to signs authorized by Subsections 51A-7.1727(c), (d) or (i).
