Illumination. All illuminated signs or lighting devices shall employ only lights emitting a constant intensity, and no sign shall be illuminated by, or contain flashing, intermittent, rotating, or moving light or lights, except to show the time and/or temperature. In no event shall an illuminated sign or lighting device be so placed or directed as to permit light or illumination to be directed towards a public roadway so as to create glare or reflection that may constitute a traffic hazard or nuisance. Signs shall be lighted only when the activity is open for business or in operation. The Township may require the applicant to provide "catalog cuts" of lighting fixtures and mounting equipment, location, spacing and aiming angles of fixtures, plots of proposed illumination intensities, nuisance and disabling glare control methods and devices, illumination on-off cycles, and anticipated light levels on adjacent parcels. Sign lights shall be pointed downwards.
