FTS 371 & FTS 371 SMART Vanguard®
Medium Intensity Red LED Aviation Obstruction Lighting Systems

Compliance and Applications

The FTS 371 series is a low-power FAA L-810/L-864 red obstruction lighting system for FAA type A1 structures that meets FAA regulations for flashing markers.

With LED replacing incandescent lighting and marker power consumption decreasing by as much as 98%, a new approach for accurate monitoring is required. The FTS 371 uses a patent-pending current feedback monitoring technology that will not fluctuate with changes in incoming power and temperature, providing consistent and predictable results.

The FTS 371 and FTS 371 SMART meet FAA AC 150/5345-43H and can accommodate both AC 70/7460-1K and 1L marker requirements. The system also meets Transport Canada CAR 621.19, ICAO Type B and Type C (6th Edition) and DGAC Mexico.
