FAA warning light systems are required on any structure above 200′ tall, and that includes flare stacks. Flares and Stacks uses 310 stainless steel for retractable warning light systems fabrication, including hoist and guide cabling. The benefit of having a retractable warning light system is purely for ease of maintenance of the lights, and being able to replace them immediately when one goes out, ensuring the system can be kept to FAA expectations at all times.
