Sealed Beam Headlamp Adjustment

SEALED BEAM HEADLAMP ADJUSTMENT






Tool Required:
J 25300-A Headlamp Aimer

Horizontal and vertical aiming of each headlamp is done by two adjusting screws that move the mounting bracket against the tension of the coil spring. These screws are located in the headlamp bezel area on sealed beam headlamp models (one above and one to the side of the headlamp).

The adjusting screw directly above the headlamp is used to adjust the horizontal position white the screw to the side is used to adjust the vertical position of the headlamp.

Using Headlamp Aimer J 25300-A, adjust the headlamps to the specifications required by state and/or local authorities. Instructions for tool use accompany the tool.

The headlamps can also be adjusted using the screen method, described earlier for composite headlamps. Follow the same directions and observe the same tolerances for the aim of the beam.
