• Direction of light: Must be directed toward the display surface

• Automatic dimming: Must be equipped with technology that automatically adjusts brightness based on ambient light conditions
• Maximum brightness: Cannot exceed 0.3 foot-candles above ambient light
• Measurement standards: Brightness measured at 100 feet for signs between 0-100 square feet

Special Sign Restrictions

In certain areas, additional restrictions apply:

• Some zones prohibit internally lighted signs, allowing only indirect lighting
• Subdivision entry signs and associated lighting must be maintained by the developer or successors-in-interest

Light Trespass and Glare Prevention

Cutoff Design Requirements

To minimize light trespass and protect neighboring properties:

• All lighting fixtures must use "cutoff" designs to prevent spillover
• Maximum illumination levels are zone-specific:
• 1 foot-candle maximum in some zones
• 2 foot-candles maximum in Commercial Corridor (CC) and other districts

Glare Restrictions

The code includes specific provisions to address glare:

• In manufacturing districts, "intense glare" must not be detrimental beyond district boundaries
• In all other districts, activities producing intense glare must be contained within completely enclosed structures
• These provisions aim to prevent both public nuisance and hazards at or beyond property lines

Parking Area Illumination

For parking areas, loading berths, and display lots:

• Lights must be designed and located to direct illumination into the interior of the property
• This requirement helps prevent light trespass onto neighboring properties and roadways

Special Area Lighting Requirements

Pedestrian-Focused Areas

In pedestrian-oriented spaces, lighting requirements focus on both functionality and aesthetics:

• Public plazas/courtyards: Must include appropriate seating, lighting, and sunlight penetration
• Through-block pedestrian connections: Walkways must feature plantings and pedestrian-scaled lighting
• Common spaces: Must provide seating and pedestrian-scaled lighting

Wireless Communication Facilities

For wireless facilities, lighting regulations balance safety with minimal impact:

• Only lighting necessary to satisfy FAA requirements is permitted on support towers
• White strobe lighting is prohibited unless specifically required by the FAA
• Security lighting for equipment shelters must be appropriately down-shielded to keep light within site boundaries

Mobile Home Parks

Mobile home parks have specific lighting requirements:

• Site plans must show provisions for lighting interior accessways
• This ensures adequate illumination for safety while maintaining residential character
