Abstract: 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.
