What are the reasons for the Hafei Saibei headlights not working?
2 Answers
Hafei Saibei headlights not working can be caused by burnt-out bulbs, overheating wires, damaged relays or combination switches; open circuits, short circuits, broken circuits, or grounding in the wiring; blown fuses or poor contact in the circuit; low battery charge; loose headlight connectors, among other reasons. Severely depleted battery: After the headlights are turned on, the battery works in conjunction with the generator to supply power. For the first two hours or so of driving, the headlights' brightness is normal, but after that, as the battery can no longer continue to supply power, the headlights' brightness decreases and fluctuates with changes in engine speed. Additionally, the engine cannot be started using the starter after it is turned off. Overheating wires: This increases the resistance in the circuit, reducing the headlights' brightness. In severe cases, the headlight circuit may short-circuit due to the melting of the wire insulation, potentially leading to burnt wiring or even a vehicle fire.
Yesterday I just encountered the problem of my Hafei Saibao's headlights not working. Don't panic! First, check the fuse box - it's that small box under the steering wheel. Pull them out to see if any are blown; this is most common in cars over 10 years old. Also check the bulbs - the low and high beams are separate, so one set might be out. Wiring harness connectors getting chewed by rodents is another frequent issue; last time I removed the front bumper and found the wires completely gnawed through. The relay is on the left side of the engine bay - if it's clicking but not working, that's the problem. Finally, check the alternator voltage; unstable voltage can cause bulbs to burn out prematurely. With older cars, you need to be extra careful, but checking these areas should basically solve the issue.
