PROBLEM TO BE SOLVED: To provide a lighting system for an agricultural work machine for controlling a light device provided in an agricultural work machine to be mounted on a tractor with higher convenience. SOLUTION: In a lighting system for an agricultural work machine applied to an agricultural work machine 2 attached to a tractor 1 to perform agricultural work, one or more lighters installed in the agricultural work machine 2 and a tractor 1 installed in the agricultural work machine 2 are provided. A controller 21 capable of receiving control information on the tractor 1 side from the tractor control unit 15 by wireless communication, a power transmission unit 33 connected to the battery 31 provided in the tractor 1 and installed on the tractor 1 side, and an agricultural work machine 2 side. The controller 21 includes a power receiving unit 41 that can receive power by wireless power supply from the power transmitting unit 33 and a power storage unit 43 that is installed in the agricultural work machine 2 and can be connected to the power receiving unit 41 to store electricity, and the controller 21 uses the received control information on the tractor 1 side. Based on this, the lighting device is controlled, and power is supplied from the power storage unit 43 to the lighting device and the controller 21.
