New L.A.N.D System has been integrated into the body of the light, This is based off a Firefighters PASS alarm system that helps us locate downed firefighters, The the added L.A.N.D. system will sound a 90 dcb alarm if your aircraft goes down and assists you in locating it. Since the light and alarm have their own power supply they are not affected by loss of power to the aircraft. Simply look at the last seen point in your flight app, and go to the area noted, look for the visual signal (strobe) and listen for the audible signal (alarm).
