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.
