Headlamp Aiming
- The headlamp aiming procedure depends on what type of beam pattern the headlamp is equipped with. Vehicles may come equipped with visual optical left (VOL), visual optical right (VOR) or SAE only (includes sealed beam type) headlamps. To identify the headlamp beam pattern, look on the headlamp lens. Molded in small letters on the headlamp lens is 1 of the following: SAE VOL and SAE VOR and SAE
- Once the headlamp beam pattern is identified, aim the headlamps using 1 of the following methods as applicable. Photometric aimers can aim VOL-, VOR- and SAE-type headlamps only. This is the preferred method of headlamp aiming. Visual or screen method aiming can be used to aim VOL-, VOR- and SAE-type headlamps only. Mechanical aimers cannot be used with VOR- or VOL-type headlamps. Aerodynamic lamps that can be aimed mechanically have 3 nibs molded into the lens of the lamp.
Photometric Aiming
- For the photometric aiming procedure, refer to the appropriate photometric headlamp aimer instruction manual.
Screen Method Aiming
ALL HEADLAMP TYPES
Note. Horizontal aim is not necessary for VOL or VOR headlamps.
Note. Consult your state vehicle inspection manual for recommended tolerance ranges for visual aiming.
Note. The sight shield may need to be positioned or removed for access to the adjusters.
