A bi-functional headlamp for a vehicle is provided. The bi-functional headlamp implements a high beam mode and a low beam mode by adjusting a movement of a shield of a headlamp. The bi-functional headlamp reduces the occurrence of impact and noise caused by an operation of opening and closing the rotary shield by maintaining contact between a shock absorber component that reduces operational noise of the rotary shield and one side of the rotary shield.

Bi-functional headlamp for vehicle

Disclosed is an aspherical lens module of a vehicle headlamp configured such that a position light function is added to the existing functions of a low beam or high beam without increasing the size of the lamp module. Further, the aspherical lens module of a headlamp is configured such that the quantity of required light of a low beam or high beam is not reduced when the position light function is added to them.
