How to repair common faults of car lighting fuses?

If the contact of the bimetallic fuse is poor, it is easy to experience the phenomenon of alternating headlights and side lights turning on and off when driving at night; If the electric horn does not sound when parking, and the sound is normal when driving, the cause should be found by the fuse (or contact) installed next to the fuse box (button) in the driver's cab. It relies on two contacts to connect the circuit. Once the contacts are loose, burned, or poorly connected, it can cause the circuit to be abnormal, especially if the contact is difficult to find and is often overlooked. With the prolongation of fuse usage time, it is easy to cause poor contact faults. During operation, the contact looseness is caused by vibration, and the entire vehicle's lights are sometimes off, sometimes on, and sometimes off. After encountering this phenomenon, the internal repair (good contact) can eliminate the fault.

In the use of vehicles, fuse erosion is one of the common faults, which must be promptly identified and repaired. Regular maintenance, adjustment, and maintenance of the lighting safety device should be carried out, and if necessary, new parts should be replaced to truly protect the electrical system.
