Summary
South Gate makes it unlawful to shine or reflect light through a neighbor's residential window or door with enough intensity to offend a reasonable person, enforced only after a resident complaint.
It shall be unlawful for any person, other than a municipality or public utility engaged in street lighting, to operate a light bulb, light source, or any other light emitting or light reflecting device in such a manner that the light emitted therefrom shall shine or reflect upon or through a window or door of a residential structure used for human occupation with such an intensity as to offend a reasonable person not personally involved in a dispute with neighbors...

Full Breakdown
The general code's light emissions chapter bars anyone other than a municipality or public utility doing street lighting from operating a light bulb, light source, or other light-emitting or light-reflecting device so that it shines or reflects onto or through a window or door of an occupied residential structure with an intensity that would offend a reasonable, uninvolved person. An exception applies where the light level is imminently necessary for health or safety and there's no less offensive way to achieve it. The city enforces this only on a resident's complaint, and only after first warning the violator and giving them a chance to fix it; violating it is an infraction.
Violations & Fines
Violation is an infraction. The city enforces only on a neighbor's complaint and issues a warning with a chance to correct before citing.
