The invention relates to a wind farm flight lighting system and a wind farm (112) having such a wind farm flight lighting system and a method for lighting a wind farm (112). For this purpose, the invention comprises a plurality of flight lighting devices (30) and at least one transmitting station (22), wherein electromagnetic waves and / or sound waves can be emitted by the transmitting station (22). The number of receiving stations (20) is at least a multiple of the number of transmitting stations (20). Furthermore, the invention comprises at least two receiving stations (20) for receiving electromagnetic waves and / or sound waves and an evaluation device (24) for detecting flying object positions. The evaluation device (24) detects flight object positions by evaluating transmitted and received electromagnetic waves or sound waves, in particular by determining the transit time. In addition, the wind park flight lighting system comprises a switching device (28) for switching on or off at least one of the flight beacon devices (30) as a function of the flight object positions detected by the evaluation device (24).
