Claim:
A vehicle headlight to form a low beam in front of a vehicle, the vehicle headlight comprising: a projector lens having an optical axis that extends in a front-back direction; a bulb disposed in a back direction from the projector lens, the bulb having a bulb axis that extends in a direction approximately perpendicular to the optical axis; a reflector disposed to cover the bulb from behind, the reflector having a main reflection surface configured to reflects light emitted from the bulb in a front direction during operation of the bulb, a shade disposed between the projector lens and the bulb, the shade configured to block a part of light received from the main reflection surface during operation of the bulb; a first additional reflection surface disposed in the front direction from the bulb, the first additional reflection surface configured to reflect light emitted from the bulb toward a space that lies ahead of an end of the bulb in a bulb-axis direction during operation of the bulb; and a second additional reflection surface disposed in the space, the second additional reflection surface configured to reflect light received from the first additional reflection surface in the front direction toward the projector lens during operation of the bulb, wherein a top end portion of the shade is bent in the back direction to form a cutoff line for the low beam with a back end edge of the top end portion; and the first additional reflection surface is disposed lower than the top end portion and further in the front direction as compared to the back end edge.
