Why are both the high and low beams of Jinbei headlights not working?
2 Answers
Jinbei front headlights both high and low beams not working reasons are as follows: the bulb may be damaged and should be replaced. The high beam combination switch may have malfunctioned and needs to be replaced. Poor contact in the wiring behind the headlights, unplug the wire connector and clean it with an eraser before reconnecting. Below is an introduction to the functions of car lights: Car headlights: used for road illumination during nighttime driving. High beams: high-angle and long-distance illumination to improve visibility and expand the field of view. Width indicator lights: indicate the width of the vehicle to alert other drivers. Width indicator lights are used during evening driving to make the vehicle visible to others. Low beams: low-angle and short-distance illumination to clearly distinguish objects, with a clearly 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 less noticeable.
I've been repairing cars for over twenty years, and issues like this with Jinbei are nothing new. When both high and low beams go out completely, it's most likely a blown fuse or a burnt-out bulb. First, check the fuse box to see if the corresponding fuse shows any signs of blackening—if it's blown, replace it with a new one. A short circuit in the wiring can also be the culprit, possibly due to loose connections or rodent damage cutting off the current. If the relay is faulty, the headlights may flicker once and then go out—this requires testing with a multimeter to check for continuity. Don’t forget to inspect the alternator’s voltage stability; excessive voltage can easily burn out bulbs. I advise against DIY repairs to avoid electric shock—just take it to a certified repair shop for a safe and hassle-free fix, preventing any roadside incidents that could affect the entire vehicle's electrical system.
