Abstract: A vehicle lamp including a projector headlight for a low beam can include a light source, an ellipsoidal reflector, a projector and shade. Light emitted from the light source can form a fundamental light distribution pattern from the projector lens via the ellipsoidal reflector by shielding an upwards portion of the light with the shade. The shade can form respective thin blurred parts on and/or underneath a horizontal cut-off line for both a driving lane portion and an oncoming lane portion using a top edge line and a top surface of the shade. Therefore, a contrasting difference between the upper and lower sides of the horizontal cut-off line can be reduced so as to be able to conform to a light distribution standard for a headlight. Adjustment of the light distribution pattern can be facilitated due to tonal difference between the horizontal cut-off line of the driving lane and the oncoming lane.
