What are the reasons for both high and low beams not working?

[MacHenry]

The reasons for both high and low beams not working are: first, the headlight bulb may be burnt out - simply replace it with a new one. Second, the fuse for the right headlight bulb may be blown (fuses are prone to burning out). Third, the headlight wiring may be disconnected, preventing power from reaching the bulb. It is recommended to first check the bulb and fuse. Definition of automotive headlights: Automotive headlights, also known as car front lights or LED daytime running lights, serve as the "eyes" of a vehicle. They not only relate to the external image of a car owner but are also closely tied to safe driving at night or under poor weather conditions. The use and maintenance of car lights should not be overlooked. Precautions for using headlights: With the increasing number of vehicles on the road, the quality of drivers varies greatly. When encountering inconsiderate drivers, try to use headlights and horns reasonably to send appropriate "warning" signals. Avoid adopting a "tit-for-tat" approach. Experienced drivers often advise against driving out of anger, as road safety should always be the top priority.
