Answer:Our warranty allows for a minimum of 5 years of operation while ensuring the beacon meets the FAA"s minimum photometric requirements. LED"s do not "burn out" similar to incandescent. An LED will have a slight degradation of light output with use. This is similar to the degradation of a strobe tube.
