What are the symptoms of a failed headlight?


The symptoms of a failed headlight:

1. After a headlight is switched on during a drive at night, it is bright in the first two hours of operation, and then gradually grows darker, the light intensity varying with engine RPM. If the engine is turned off, it can’t be restarted with the starter. This failure may persist even the next day.

2. After a headlight is switched on, its wires become hot, with a smell of burning plastic or bakelite. In serious cases, the harness may be burned up or a fire accident may occur.

3. After a headlight is switched on of off, it won’t light up or go out.

4. The fuse is blown and the ammeter is burned out. Even the charging circuit may be burned out.

5. If many electrical devices are used or if the generator remains overloaded for an extended period, the generator’s diodes and coils may be burned out, preventing further power generation.
