Why is the low beam working but the high beam not?

[MacErin]

When the low beam is working but the high beam is not, it indicates that the high beam bulb is damaged. In vehicle lighting systems, there are integrated headlights that combine both high and low beams, as well as separate high and low beam headlights. This situation involves separate headlights where the high beam bulb controls the high beam, and the low beam bulb controls the low beam, operating under separate controls. Car headlights, also known as automobile front lights or LED daytime running lights, serve as the 'eyes' of the car. They not only affect the owner's external image but are also crucial for safe driving at night or in adverse weather conditions. Therefore, the use and maintenance of car lights should not be overlooked.
