Disclosed is a beam angle display device for automobile headlights to display the accurate angle of the beam. The housing(12) and the lens(11) of the head lamp are assembled; the beam angle of the reflector(14) is inspected and adjusted by beam angle adjustment device(1); a reflector is rotated on the hinged axis within housing(12); a bracket(1a) is at rear of the housing(12); reflector is installed through the bracket(1a) and the housing(12); a longitudinal feed lever(1b), adjustment device(1d), rotating rod(1e), and a movable quadrant(1g) are attached to rear of the reflector so as to move longitudinally. The movable quadrant(1g) comprises a through hole(1h), a through hole(1i) connected to the end of the rotating rod(1e), and a scale(1j) by which the relative beam angle is identified.
