(2) The light source shall be indirect, diffused or shielded type fixtures, installed to reduce glare and the consequent interference with boundary streets and adjacent property.

(3) Fixtures shall be attached to buildings or mounted on poles in such a manner and at such a height that light is not directed at a residential use.

(4) Maximum height of lights shall not exceed 35 feet.
