Full Breakdown
Under the Harlingen zoning code's sign lighting standards, any illuminated sign within 200 feet of a residential lot line must use diffused or indirect lighting design specifically to keep direct light rays from spilling into adjoining residential districts or lots. A separate provision requires external sign lighting (floodlights, goose-neck reflectors) to be aimed at the sign face and shielded so beams don't hit the traveled roadway, and caps sign illumination at one footcandle measured at the property line.
Violations & Fines
Signs illuminated in violation of the shielding, diffusion, or footcandle limits are a zoning code violation, enforceable by the city's code compliance/building department alongside the sign permit process; noncompliant lighting can be ordered corrected or the sign permit revoked.
