Solar Obstruction Lights

Lower energy requirements with our reliable solar obstruction lights. Flash Technology’s solar-powered obstruction lights for United States clients feature lights that will shine for 7 consecutive nights if no charging occurs during the day, compliant with FAA Engineering Brief No. 76. We also offer a solution for those aviation applications that do not require the FAA minimum 7 days of autonomy, typically for clients outside the US. Solar-powered lighting systems are ETL certified to FAA AC 150/5345-43H, ICAO low intensity types A and B and DGAC standards.
