Lighting fixture for bicycle

A bicycle lighting fixture, comprising a housing defining therein an accommodation chamber, a reflector mounted in said accommodation chamber and a light source mounted in said accommodation chamber and adapted to emit light onto said reflector, wherein said reflector comprises a curved reflecting surface facing toward the outside of said accommodation chamber, said curved reflecting surface comprising a plurality of reflecting surface areas disposed at different elevations and a terrace surface connected between each two adjacent said reflecting surface areas, wherein when said light source emits light onto said reflecting surface areas of said curved reflecting surface, said reflecting surface area at the lowest elevation reflects the light emitted by said light source in horizontal, and the other said reflecting surface areas reflect the light emitted by said light source at a respective downward slope angle, the downward slope angle of the reflected light from a relatively higher one of said reflecting surface areas being relatively larger than the reflected light from a relatively lower one of said reflecting surface areas.
