The Department of Transportation, specifically the Federal Aviation Administration (FAA), is seeking industry input on the draft specifications for the ALSF-2 LED Light Assembly, which is integral to the High-Intensity Approach Lighting System with Sequenced Flashing Lights. The FAA aims to refine the performance specifications for these LED assemblies, which are intended to replace traditional incandescent lamps, ensuring they meet stringent operational tolerances and environmental resilience. This initiative underscores the FAA's commitment to modernizing aviation lighting systems to enhance safety and operational reliability.
