The invention relates to the technical field of automobile lamps, in particular to an automobile headlamp dimming system. The system comprises a light source module, a horizontal dimming mechanism anda vertical dimming mechanism, wherein the light source module is installed in the lamp through the light source module bracket; the horizontal dimming mechanism comprises a horizontal dimming motor and a horizontal dimming bracket; the horizontal dimming bracket is rotatably connected with the light source module bracket through a connecting piece; the horizontal dimming motor is connected with the horizontal dimming bracket through key fit; the vertical dimming mechanism comprises a vertical dimming motor, a dimming rod and a transmission screw rod; the vertical dimming motor is connected with the transmission screw rod through a coupler; the dimming rod moves through a thread on the transmission screw rod; the front end of the dimming rod is spherical and is clamped with the spherical seat; and the spherical seat is fixedly connected with the light source module bracket. The problems that in the prior art, the horizontal irradiation angle of an automobile headlamp cannot be adjustedalong with the rotating direction of an automobile, and the vertical irradiation angle of the headlamp cannot be adjusted along with the up-down ramp of the automobile can be solved.
