Abstract
A leveling arrangement for a vehicle headlamp that includes a slot formed in the
upper portion of the reflector member in which a spirit level member is located and combined with a
spring clip which is fastened to the reflector member and to one end of the spirit level member and
includes a leaf spring which continuously biases the other end of the spirit level member in one direction
so that an adjustment screw threadably received by the spirit level member permits the aforementioned other
end of the spirit level member to be raised or lowered for providing calibration of the spirit level member
relative to the optical axis of the reflector member.
