Visual Aiming Procedure

WARNING: This page is about a different car, the 2003 Pontiac Vibe. However, it is still accessible from the selected car via links, so may be relevant.

All equipment for testing headlamps must comply with the SAE Recommended Practice for Headlamp Inspection Equipment.
If you use a headlamp testing machine, the machine should give results equivalent to the results obtained using the screen procedure.
The machine should be in good condition and be properly adjusted.
Use the machine in accordance with the manufacturer's instructions.
Machines that use a photoelectric cell or cells to determine aim, should also include a visual screen on which you can project a beam pattern proportional to the beam appearance, and aim on a screen at 7.62 m (25 ft).
- The screen should be plainly visible to the technician who is adjusting the headlamps.
- The screen should have horizontal and vertical reference lines in order to permit visual evaluation of the headlamp beam.
