A vehicle headlamp device can be equipped with a discharge lamp a beam switch device that is used to switch between the high beam and low beam, a light distribution switch device which broadens the horizontal light distribution in the forward direction of the vehicle during cornering, and a lighting device which supplies electric power to the discharge lamp. The light distribution switch device can be controlled such that the horizontal light distribution is broadened in the forward direction when the vehicle speed and steering angle exceed specified values. The lighting device can be controlled such that the electric power supplied to the discharge lamp increases only when the horizontal light distribution is broadened by the light distribution switch device
