FTS 350i-2 Wind Turbine Light

FAA L-864(L) Wind Farm Lighting System

The FTS 350i-2 is an FAA L-864(L) / ICAO Medium Intensity Type B aircraft warning light. A fully integrated system designed for wind turbine operators, it offers a weather-resistant polymer construction, industry-leading surge protection and Aircraft Detection Lighting System (ADLS) connectivity. Small and light, this stand-alone obstruction light does not have a controller taking up scarce space inside the nacelle.


The FTS 350i-2 complies with FAA AC 70/7460-1M and 1L requirements for turbines with rotor tip heights less than 699 feet and is certified to AC 150/5345-43J (infrared).

  • Aircraft Detection Lighting System (ADLS) interface (lighting control module sold separately)
  • Surge immunity of 25kA to withstand 99% of all lighting strikes
  • Fully integrated system – no external controller
  • Easy to carry and install on turbines due to extremely low weight
