If a sign has a sign area of more than 20 square feet, it shall not have a scrolling message.
C. No sign will be permitted which is not effectively shielded so as to prevent beams or rays of light from being directed at any portion of any public street or which is of such intensity or brilliance as to cause glare or to impair the vision of the driver of any vehicle, or which interferes 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.
E. Signs which contain, include or are illuminated by any flashing, intermittent or moving light(s) are prohibited, except those giving public service information such as time, date, temperature, weather or similar public service information.

G. The aggregate output of the light sources from any sign shall not exceed 500 initial lumens per square foot of sign face per side. LED sign surfaces or other internally illuminated sign faces shall not be allowed if they exceed 100 square feet per side and are located within 400 feet of a residential district. Off-premises signs with LED or other internally illuminated sign faces that are within 300 feet from a residential district and that face onto that residential district shall not be internally illuminated between 11:00 p.m. and 6:00 a.m.
