Every new or replaced lighting fixture on any parcel in any business district or on any parcel owned by the Village of Brightwaters, whether attached to a structure, freestanding, or affixed to a utility pole, shall be directed downward with a zero-degree horizontal cutoff to the illumination. No reflectors shall be mounted within 20 feet of the fixture to redirect the light emanating from the fixture. Replacement of a bulb within an existing fixture is not a replacement of a fixture and thus not governed by the above standards.
