Oakley FAQ
Can I have a bright floodlight in my backyard?
It must be shielded so the bulb is not visible from neighbor's yards and not spill significant light onto adjacent properties. Motion-activated security lights are favored over constant-on.
Are holiday lights allowed?
Yes. Seasonal decorative lighting is generally exempt between specified dates (typically Nov 1 – Jan 15) from intensity and cutoff requirements.
What about solar garden lights?
Low-intensity solar path lighting is generally exempt from the shielding requirements because of their low lumen output.
