Car light usage is divided into daytime running lights, high beam and low beam lights, and turn signals. The specific introductions are as follows: Daytime running lights: Daytime running lights, also called position lights, serve to make the four corners of the vehicle visible to others, with lower brightness than headlights. These lights should be turned on during rain, dim lighting conditions, or in underground parking lots. High beam and low beam lights: High beams have a higher projection angle than low beams, allowing them to illuminate objects that are higher and farther away. Low beams are generally used on roads with street lighting. High beams are used on roads without lighting and are often employed to illuminate road signs in the distance. Turn signals: Turn signals must be activated in advance when the vehicle needs to turn. Only after confirming there are no vehicles approaching from behind should the turn be made. Avoid turning immediately after signaling without checking the rear situation. Before overtaking, activate the left turn signal and confirm that the road ahead meets overtaking conditions. If a vehicle behind intends to overtake, the right turn signal can be activated to indicate permission. At U-turn or turning lanes before traffic lights, unless you are first in line, there is no need to keep the turn signal on continuously. It is not too late to activate the turn signal when the vehicle actually turns.
