Mead Valley FAQ
What does "fully shielded" mean for my outdoor light?
Under Ordinance 655 Sec. 4.J, a fully shielded fixture is built so that all of its light is projected below the horizontal plane through the fixture's lowest light-emitting point - meaning no light escapes sideways or upward.
Is there a county rule for a neighbor's light shining on my property?
Within the Palomar light-pollution zones, Ordinance 655's shielding and curfew rules apply. Outside those zones the County has no general numeric trespass standard, and such disputes are usually handled as a private nuisance matter.
