How to Adjust Headlight Focus?

[GabrielleAnn]

Methods for adjusting headlight focus: It can be adjusted by modifying the light position, which is achieved by turning the corresponding adjustment knobs located at the back of the headlight. The specific parts to be adjusted and the tools required vary depending on the vehicle model, so it's necessary to refer to the particular model. Before adjustment, shine the headlights onto a wall and observe whether the light beam is misaligned, too high, or too low. Traditional halogen lights have good focus because the tungsten filament emits light when lit, with the light originating from a central point—commonly referred to as point-source lighting. This point-source light is refracted by the reflector bowl, concentrating and projecting forward while evenly spreading across the road surface, ensuring sufficient brightness for forward visibility.
