How High Should Headlights Be Aimed?

According to the test and data check from AUXITO, the headlight beam irradiation position can achieve the standard lighting and not dazzle the oncoming car if it can meet the following requirements.

1. Motor vehicles (except transport tractors) in the test headlights low beam irradiation position, headlights at 25 feet from the screen, the height of the midpoint of the beam should be 2-4 inches downward offset from the headlight's reference center height, its horizontal position to the left and right offset shall not exceed 100mm.

You can also refer to the rules specified in SAE J599, if your car's headlight height is less than 36in, you can directly take the horizontal height of the headlight as the base without offsetting down a distance.

2. If the vehicle is a dual-beam light with high beam and low beam, the low beam light is the mainly adjusted. Adjusting your low beams will also reset your high beams to where they should be, as most cars don’t have a separate adjustment for the high beams. But for lamps that only can adjust the single beam with high beam light, adjust it directly.

3. You can always check the owner's manual of your model or Lighting Inspection Code for low beam cut-off height adjustment to get the standard lighting.

How To Aim Headlights?

1. Preparation Before Adjustment

1) Vehicle Preparation For Headlight Aim Adjustment
Ensure that the vehicle has no damage or deformation around the headlights.
Make sure that the different oil types in the vehicle are all filled to the specified levels.
Make sure that the coolant is filled to the specified level.
Inflate the tires to the appropriate pressure.
Place the spare tire, tools, and jack in their original positions.
Unload the vehicle.(But If you regularly carry around heavy equipment or supplies, place them in the vehicle as well.)
Have a person who weighs approximately 55 kg (121 lb) sit in the driver seat.

2) Environmental Requirement
The test should conduct on sufficiently flat ground(not including uphill, downhill and rough ground)
