1. A light distribution assembly, comprising a first lens, a second lens, a first kit, a second kit, and a driving part, wherein: each of the first kit and the second kit is in a hollow through cylindrical shape having two opposite openings, the first lens is sleeved in the first kit, the second lens is sleeved in the second kit, the second kit is sleeved in the first kit and is rotatable relative to the first kit to allow the second lens to be rotatable relative to the first lens, at least one of the first lens and the second lens is a polarizing lens to change a light distribution path of the light distribution assembly, the driving part is fixedly connected to an end surface at an opening of the second kit, the end surface of the second kit that is connected with the driving part is away from the first lens, the driving part extends radially outward from the second kit,
wherein the driving part includes a radial extension portion and an axial extension portion, the radial extension extends radially outward from the end surface of the second kit and the driving part is located outside the first kit, and
the first lens and the second lens are the same optical elements and are symmetrically assembled to form the light distribution assembly.
