Adjusting headlamp headlight height: how to do it

Among the obvious signs that the headlights are not properly geared is the fact that cars crossing them flash their headlights to signal that your lights are blind, or the fact that the road to be walked is heavily illuminated for only 6 meters or down there, which means that the headlights are turned too far down.

But a wrong orientation of the car’s headlights is not your fault. Any problems with suspensions or heavy loads may also change the trim of the vehicle and slightly shift one or both headlights, perhaps perfectly aligned previously. A collision with a pebble on the road is able to move an optical array and misalign the lights.

One way to tell if the headlights are properly turned is to park the vehicle on a flat surface and shine the headlights on the garage door or on a wall 6-7 meters ahead (some vehicles may require a different distance). The top of the glare passing glare on the wall must be equal to or slightly lower than the center of the headlamp lens for most vehicles.

The light cone must be positioned higher on the right side (ie on the passenger side) to illuminate road signs and, on the other hand, lower on the driver’s side to avoid blinding drivers coming from the opposite direction. This should give a good idea if the lights on both sides are properly addressed.

Another method is to place the vehicle within 1.5 meters of the wall and use adhesive tape to mark the vertical and horizontal light beam centers on the wall. Then move the 8-meter vehicle. Light beams should be about the same height. The vehicles have a adjusting screw or bolt on the optical headlight adjustment unit, and some also have a horizontal orientation adjustment. Some vehicles also have a bubble level to help in optimal adjustment.

On some vehicles there may be little or no room to reach regulators without removing other parts, such as battery. In addition, in order to obtain accurate reading the vehicle must be really flat, ground clearance should not be affected by damaged suspensions or by the presence of goods or other heavy materials on the vehicle, and the vehicle must be perpendicular to the surface on which it is it is about to orient the headlights.
