From Structures. Light from enclosed structures shall be shielded or directed in such a way that glare is not visible at any point on any boundary line between a residential and nonresidential district or at or beyond any point on any property line or street line within a nonresidential district.

Area Lighting. Area lighting, including that used for production activities and protective purposes, driveways, loading and unloading and parking, shall be located so that glare will not become a nuisance to adjoining properties, adjoining districts or to any adjoining public right-of-way. All permitted lighting shall be arranged so as to be directed upon the property from which the light originates so as to not directly illuminate any contiguous property.

Illumination of production activities shall be buffered so that direct illumination source will not be visible to adjoining properties.

Advertising Lighting. Advertising lighting, including all lighting which is used for directing attention, shall be permitted where the source of illumination shines directly toward the sign without producing glare or shines directly toward a building, cluster of shrubs, fountain or other point of interest, not toward any point off the property. No lighting of intermittent intensity or flashing lights will be permitted. No lighting will be permitted which is directed skyward solely for the purpose of advertising or drawing the attention of the public.

This subsection 16-23.4 shall not be construed to prohibit lighting required by police or other enforcement agencies for the safety and protection of employees and of the general public.
