What is the headlight in Subject 3?

[ValentinaRose]

Car headlights, also known as car front lights or car LED daytime running lights, include high beams, low beams, and turn signals. High beams: High beams should only be used when there is no other light around. They can be used when driving on unlit highways at night or in rural areas without streetlights to expand the field of vision. However, when encountering oncoming traffic, it is necessary to switch to low beams for safety and courtesy. Low beams: Low beams must be turned on when driving in areas without streetlights at night, during dusk when it is darker, or at dawn when visibility is low. Even during the day, low beams should be used in heavy fog, snow, or heavy rain when visibility is poor. Additionally, in some areas with insufficient lighting, low beams should also be activated. Turn signals: The most basic function of turn signals is to indicate turning intentions to other vehicles and pedestrians, alerting them to be cautious. Sometimes, turn signals can also serve as auxiliary lighting in narrow spaces, helping drivers observe obstacles on either side.
