safety beacon
Distress light device
A safety beacon is a device that emits light or radio signals to mark location during emergencies or hazardous conditions.
Beacons help rescuers locate people in distress—hikers carry personal locator beacons, boats deploy emergency beacons when sinking.
The term also covers stationary warning lights marking obstacles or safe passages: The safety beacon on the tower flashes at night.
