What Causes the Headlight Height Adjustment to Malfunction?

[VanRuby]

The malfunction of the headlight height adjustment is caused by damage to its motor. Adjustable headlight height refers to modifying the headlight's angle to achieve the optimal illumination distance, thereby preventing potential hazards. This is a safety feature in vehicle lighting, typically utilizing an electric motor to adjust the headlight height electronically. Below is an introduction to headlight height adjustment: 1. The headlight height adjustment knob is usually located on the left side of the dashboard, near the light control switch. 2. Generally, the knob is marked with numbers from 0 to 3, where a higher number indicates a lower height. In most cases, the 0 position is sufficient. 3. Position 0 is the default setting, representing the horizontal height suitable for when the front seats are occupied and the trunk is empty. Positions 1-3 are appropriate for when the vehicle is fully loaded with passengers and cargo.
