The red aircraft beacon is usually mounted on the vertical fin (Cessna and Murphy types) and switched on to indicate a 'live' aircraft, i.e. with the engine about to start or already running.
On this page we show you the installation of the Kuntzleman Electronics, Inc - Red LED Aircraft Beacon in the top fairing of the vertical fin of a Murphy Elite aircraft.
LED Beacon instructions from KEstrobes, with an inner and outer ring plus mounting bracket.
