A headlamp arrangement designed and configured to slow light-and-shade changes in a light-and-shade boundary portion of a light distribution. A vehicle headlamp 1 includes a reflector 2 having a substantially spheroidal reflective surface 2a, a light source 3 disposed at a first focal position F1 of the reflector, a projection lens 4 that forwardly projects the light reflected from the reflector 2 and that is disposed in front of the light source, a cutline-forming shade 5 whose upper edge 5a is disposed substantially at the focal position f of the projection lens, and a dimmer shade 6 whose front end portion 6a is positioned closer to the reflective surface than it is to the second focal point F2 of the reflector. The dimmer shade is disposed above the optical axis x-x of the reflector. |
