About this part
Hand tool for aiming classic BMW headlamps that use a 3/8-inch square plastic adjuster, including E28, E24 and E23 lamps. The source provides 60, 100 and 150 mm shaft options and recommends a stiff filament. BMW numbers 63121362049 and 63121369857 identify the nut and screw being adjusted, not the printed tool, so no OEM number is assigned.
