Work machine

The working machine (2) has working equipment (30,32) and an illumination unit for illuminating working area of working equipment. A detection unit detects position of two relatively movable units of working machine and/or steering angle of working machine. A control unit is in communication with detection unit such that detected position data are transmitted to the control unit. The control unit controls the illumination intensity of direction light emitted by a lighting unit and adjusts the direction light in response to the data obtained from a sensing unit. An independent claim is included for a method of operating working machine.
