PROBLEM TO BE SOLVED: To enable a user to perform confirmation of a light-distribution pattern, an irradiation area, propriety of control or the like as a result of control of a headlight control device. SOLUTION: The headlight control device (3) is provided with a control operation part (20) and an operation part (21). The control operation part determines the light-distribution pattern based on an input signal to the headlight control device and operates an operation signal for realizing the light-distribution pattern and gives it to the operation part. It simultaneously transmits the input signal and the operation signal at that time to a car navigation device (2). The operation part operates the headlight according to the operation signal. A control circuit of the car navigation device calculates the light-distribution pattern of the headlight based on the input signal and the operation signal transmitted from the headlight control device and displays the calculated light-distribution pattern, the position of a vehicle and the azimuth of a vehicle body superposingly on a periphery map.
