Provided is a wind turbine that includes a tower, a nacelle, a plurality of light sources mounted within the tower and the nacelle, and a wireless lighting control system. The wireless lighting control system includes a first locally controllable switch for controlling power to the plurality of light sources and a second locally controllable switch for controlling power to the plurality of light sources. The first and second locally controllable light switches are located remotely from each other. The wireless lighting control system further includes a remotely controllable light switch located at each of one or more of the light sources. The remotely controllable switch is configured to wirelessly receive a switch-on signal generated in response to manipulation of at least one of the first and second locally controllable switches, and switch on power to the corresponding light source in response to receiving the switch-on signal.
