A bending beam headlamp is provided to remove a second bulb or a second reflector in an advanced headlamp system by using a multi filament bulb. A reflector has a reflection surface. The reflection surface emits a light of a main light source into a headlamp beam shape. A lamp bulb includes a horizontal extension axis line and a light transmission wall. The light transmission wall defines an enclosed volume, and surrounds a first filament(50), a second filament(60), and a third filament(70). An electric connection part selectively supplies a power to the first through the third filament. A control system supplies a power to the second filament corresponding to a first conversion condition and the third filament corresponding to a second conversion condition in response to direction conversion signals of vehicles. The second filament is displaced into the first filament side. The third filament is horizontally displaced into the first filament side. |
