At least two LED lights are provided on the circuit board, and the lens is installed on a fixed base of the main body, and the circuit board is installed in a concave chamber of the lens.

A high beam passing area and a low beam passing area are formed on the lens, and at least two LED lights on the circuit board correspond to a high beam passing area and a low beam passing area of the lens, respectively. The heat dissipating unit is installed in the soft unit of the main body, and a plurality of heat dissipation fins are installed on the outer circumferential surface of the heat dissipating unit. At least two LED lights on the circuit board project the light source respectively to the high beam passing area or the low beam passing area on the lens.
