Marking and Lighting of Wind Turbine structures is intended to provide day and night conspicuity.  Wind Turbine Farms (three or more wind turbines of greater than 200ft AGL) must comply with FAA requirements.  Wind Turbine Lighting Requirements are published by the FAA in Advisory Circulars.  This page provides an overview of these requirements as well as a list of applicable Advisory Circulars and Engineering Briefs.  ITL, LLC offers a wide range of  Wind Turbine Obstruction Lighting Systems  to aide in compliance with FAA regulations.
