A bicycle lamp with a high beam and low beam switching function comprises an LED light source set and a special-shaped lens. The LED light source set comprises a low beam light source and a high beam light source. The special-shaped lens comprises a lens main body, a light incident surface, a light emergent surface and a light condensing surface, wherein the light incident surface comprises an auxiliary light incident part. When the low-beam light source is turned on, the scattered light rays are gathered by the auxiliary light incoming part and the light gathering surface. According to the bicycle lamp with the high beam and low beam switching function, the low beam light source, the high beam light source and the special-shaped lens are arranged, so that light emitted by the low beam light source or the high beam light source forms a low beam light source light spot set or a high beam light source light spot set on the horizontal ground. By arranging the auxiliary light inlet part, light emitted by the light source can be collected as much as possible, and effective illumination light is formed.
