31-48   Lighting
Off-premise signs may be illuminated subject to the following restrictions:
   A.   Signs which contain, include, or are illuminated by any flashing, intermittent, or moving light or lights are prohibited if such signs interfere with traffic safety. Reflective surfaces or devices on sign faces, and multiple-faced signs, with illumination, are permitted, provided such signs do not interfere with traffic safety and comply with subsections (C) and (D) of this section.
   B.   Electronic variable message signs giving public information such as, but not limited to time, date, temperature, weather, or other similar information, and commercial electric variable-message signs which function in the same manner as multiple-faced signs are permitted, provided such signs do not interfere with traffic safety and do not resemble or simulate traffic control or safety devices or signs.
   C.   Signs must be effectively shielded to prevent beams or rays from being directed toward any portion of the traveled ways, and must not be of such intensity or brilliance to cause glare or impair the vision of the driver of any motor vehicle or otherwise interfere with any driver's operation of a motor vehicle.
   D.   No sign shall be so illuminated that it interferes with the effectiveness of or obscures an official traffic sign, device or signal.
