Whenever painting or lighting is required, the Commission will generally assign specifications in accordance with the FAA Advisory Circulars ref- erenced in § 17.23. If an antenna instal- lation is of such a nature that its painting and lighting in accordance with these specifications are confusing, or endanger rather than assist airmen, or are otherwise inadequate, the Commission will specify the type of paint- ing and lighting or other marking to be used in the individual situation.

a) The requirements found in § 17.23 relating to painting and lighting of antenna structures shall not apply to those structures authorized prior to July 1, 1996. Previously authorized structures may retain their present painting and lighting specifications, so long as the overall structure height or site coordinates do not change. The Antenna Structure Registration re- quirements found in § 17.5, however, shall apply to all antenna structures that have been assigned painting or lighting requirements by the Commis- sion, regardless of prior authorization.
