What are the reasons for both high and low beams of Jinbei headlights not working?

[DeJude]

Jinbei headlights both high and low beams not working reasons are as follows: 1. The bulb may be damaged and should be replaced. 2. The high beam combination switch may be faulty and needs replacement. 3. Poor contact of the wiring behind the headlight, unplug the wire and clean the contact with an eraser then reconnect. The following is an introduction to the functions of car lights: 1. Car headlights: Used for road illumination during night driving. 2. High beams: High beams have a high angle and long distance, improving visibility and expanding the observation field. 3. Width indicator lights: Indicate the width of the car to alert other vehicles. Width indicator lights are used during evening driving to make the car visible to others. 4. Low beams: Low beams have a low angle and short distance, clearly distinguishing objects, with a visible illuminated area of 2-3 meters in diameter on the ground. The area from the beam cutoff line to 30-40 meters mainly relies on ground-reflected light, where brightly colored objects can be distinguished, but stationary dark-toned objects on the road are hard to notice.
