1. A wind turbine comprising:
a marking light system comprising at least one marking light for aerial traffic, a data source, which is at least one light sensor, and a marking light controller for controlling the at least one marking light according to data of the data source, which is sensor data of the at least one light sensor,
a wind turbine controller,
a power line for at least the at least one marking light and/or at least one control line connecting the marking light controller to the wind turbine controller, and
wherein the wind turbine further comprises a switching arrangement comprising at least one switching unit in the power line or the control line, wherein the switching arrangement is independent of the marking light controller, wherein the switching unit is configured to receive a detection signal from an air traffic detection system associated with the wind turbine and to turn the at least one marking light on or off when the detection signal indicates air traffic or no air traffic, respectively, in an area around the wind turbine.
