The standards and criteria for lighting of outdoor advertising authorized to be erected and maintained in zoned or unzoned commercial or industrial areas adjacent to the interstate and primary highway systems are:

(2)External lighting, such as floodlights, thin - line and gooseneck reflectors, is permitted, if it is shielded so as to prevent the direction of rays of light to any part of the main - traveled way;
(3)No lighting is permitted which is of such brilliance or intensity so as to establish glare or reflection which would interfere with the effectiveness of any official traffic control device or official sign or interfere with the motorist's view of traffic conditions; and
(4)A changeable message sign is permitted as an off - premise sign, regardless of the technology used, if the message is changed not more than once every six seconds and if the message is not continuously scrolled.
