Lawton, OK Outdoor Lighting: Dark Sky Rules (2026)

Section 6-1-5-187 governs site lighting reviewed as part of a development's site plan, most often the parking-lot and security lighting for commercial, multi-family, and institutional projects. The section states that site lighting is not mandatory, but once a project provides it, the fixtures must meet specific shielding rules rather than being left to the developer's preference. The core shielding requirement is direct: light sources, meaning the light bulbs themselves, shall not be visible, and fixtures must be shielded so the light reflects down onto the ground rather than spilling onto adjacent streets or neighboring property.

The section separately prohibits any fixture whose glare or distraction interferes with traffic movement on an adjoining street or otherwise creates a traffic hazard. Beyond shielding, the same section folds in a design-integration expectation, that lighting should enhance the site's aesthetics and be integrated with the architecture of the buildings, and it requires the height, spacing, mounting location, and fixture type to be reviewed at the site-plan stage rather than installed ad hoc. For fixtures putting out more than 2,000 initial lumens, roughly a 150-watt incandescent bulb's output, the section requires full cutoff optics, meaning no light escapes above ninety degrees from vertical, the same physical design most dark-sky ordinances rely on even though this section frames the goal as protecting adjacent residential properties and traffic safety rather than the night sky itself.
