Headlamp Aiming

HEADLAMP AIMING

1. 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) or visual optical right (VOR) headlamps. To identify the headlamp beam pattern, look on the headlamp lens. Molded in small letters on the headlamp lens is one of the following:
- VOL and SAE
- VOR and SAE

2. Once the headlamp beam pattern is identified, aim the headlamps using one of the following methods as applicable.
- Photometric aimers can aim VOL- and VOR- headlamps. This is the preferred method of headlamp aiming.
- Visual or screen method aiming can be used to aim VOL- and VOR- headlamps.
- 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.
