Abstract

A headlight device and a bending headlight module thereof are provided. The headlight device includes a main headlight module and a bending headlight module. The main headlight module is capable of generating a first lighting area which is a light pattern that complies with the regulations of low beam headlamps. The main headlight module includes a main optical axis, and the main headlight module defines a horizontal plane and a vertical plane perpendicular to the horizontal plane, and the main optical axis is parallel to the horizontal plane and the vertical plane. The bending headlight module is disposed close to the main headlight module, and the bending headlight module includes a first reflecting unit, a first lighting unit, a first cut-off plate unit, and a first lens unit.
