1. A headlight controller connectable to a first headlight and a second headlight spaced apart in a vehicle width direction at the front of the vehicle, the headlight controller comprising:
a rainfall amount detection means installed in the vehicle; and
a controller installed in the vehicle, wherein the controller is connected to the rainfall amount detection means, and the controller carries out control such that when rainfall amount detected by the rainfall amount detection means is equal to or more than a predetermined value, irradiation light from the first headlight becomes relatively darker than irradiation light from the second headlight,
wherein the first headlight and the second headlight are configured to form high beam light or an adaptive driving beam,
wherein the first headlight is arranged on the same side as a driver's seat of the vehicle with respect to a predetermined position of the vehicle in the vehicle width direction, and
wherein the second headlight is arranged on the side opposite to the driver's seat of the vehicle with respect to the predetermined position of the vehicle in the vehicle width direction.
