A projector headlight for a low beam can include a first and second lighting unit. Each of the first and second lighting units can include an LED light source, an ellipsoidal reflector, a projector lens and a shade. Light emitted from the LED light source can form a light distribution pattern from the projector lens via the ellipsoidal reflector by shielding an upwards portion of the light with the shade.
