A leveling arrangement for a vehicle headlamp that includes a support portion formed
in the upper portion of the reflector member that has a spirit level member mounted thereon which is
characterized in that it includes a living hinge serving as a pivotal connection for a depending member
fastened to a substantially vertically oriented surface of the support portion so that rotation of screw
means carried by the spirit level results in pivotal movement and calibration of the spirit level relative
to the optical axis of the reflector member.
