What if the headlights are broken?
There are two types of broken headlights:
One is that the headlights are not on. The reasons for this are:
Caused by poor construction of iron.
The light bulb burned out.
Loose or corroded joints increase contact resistance.
The other is that the headlights are not on at all. The reasons for this are:
1. The power circuit is short-circuited or connected before the indicator switch.
2. Headlamp safety trip or burn out.
3. The bimetallic connector of the light switch is in poor contact or not closed
4. The indicator switch is damaged.
5. When a certain light switch is connected, some light lines will cause the bimetallic contact to open
