Dorman - HELP Headlight Adjusting Screw P/N:42161
Replace a stripped or missing headlamp aiming screw with the Dorman headlight adjusting screw, part number 42188 from the Dorman - HELP line. It is a sealed beam adjuster that lets the headlamp's aim be set and helps hold it in place. It fits many vehicles, among them the 1983-1987 Dodge Charger, 1987-1991 Dodge Dakota and 1988-1991 Dodge Grand Caravan. See the "Vehicles it fits" section for the full list.
The adjusting screw links the headlamp to its mounting. Turning it moves the lamp so the beam's aim can be changed. A lamp that won't stay aimed, sits loose, or doesn't move when the adjuster is turned can be a sign the screw is stripped, broken or missing. Inspect the adjuster and mounting before replacing, and re-aim the headlights per the vehicle's service information after installation.
