How to Remove a Sedan's Headlight?

[StArianna]

After opening the sedan's engine hood, unscrew the dust cover by turning it in the direction of the threads, then press the wire spring clip near the base to remove the headlight. Below is the working principle of headlight height adjustment: 1. Manual Adjustment: Uses a sliding rheostat to control the motor for height adjustment. The driver can adjust the light angle via the lighting knob under the dashboard based on road conditions. 2. Automatic Adjustment: Converts signals from height position sensors into voltage signals through algorithms, then the headlight control module drives the motor to adjust the headlights. The vehicle is equipped with corresponding sensors that automatically detect the dynamic balance status during driving. 3. Some models lack headlight height adjustment functionality and thus have no adjustment button. Fine-tuning can be done by adjusting the small knob on the headlight assembly.
