Abstract
A vehicle headlamp includes a lamphaving shade switching meansfor providing a desired light distribution pattern by blocking a portion of light emitted from a light source. Light distribution pattern switching controlling means controls the shade switching meansin response to receipt of an instruction of switching a light distribution pattern of the lamp. Leveling meanscontrols deflection of an optical axis of the lamp in a vertical direction. The light distribution pattern switching controlling means controls the shade switching meanssuch that a cut line is formed by a height substantially the same as that of a cut line of high beam when an instruction of switching to a light distribution pattern of 'remote optically recognizing beam' is received and controls the leveling meanssuch that the cut line is formed by a height of a cut line requested for 'middle beam'.
