What is the usage of car lights?

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.
As a seasoned driver with 20 years of experience, I believe the core purpose of automotive lighting is to enhance safety. During daytime rain, overcast conditions, or dusk, it's essential to turn on headlights or parking lights to improve visibility. Use low beams for normal nighttime driving to avoid blinding oncoming traffic; briefly switch to high beams on highways when illumination is insufficient before promptly reverting. In foggy or heavy rain conditions, activating front and rear fog lamps significantly improves visibility. Also, pay attention to lighting controls—for instance, signaling turns in advance with indicators and using hazard lights when parked. Regularly checking bulb brightness and cleaning lamp housings prevents unexpected failures. Adopting these habits dramatically reduces accident rates, especially on rural roads where they can be life-saving. Remember: vehicle lights are a driving language—standardized usage ensures safer journeys.
As a beginner driver, I was most troubled by light operations, but later mastered the basics through driving school. After starting the car, first check the dashboard indicator lights to ensure the headlights are functioning. Daily driving is straightforward: turn on low beams in dim light and use turn signals when changing direction. In foggy conditions, activate fog lights but avoid overuse, while high beams should only be used briefly on open roads to avoid dazzling others. When parked, turn on hazard lights or taillights to alert vehicles behind. I once encountered a stuck switch issue and replaced it promptly to prevent hazards. With more practice, I grew confident using lights in rainy conditions—they became a protective shield, enhancing overall driving safety. New drivers shouldn’t panic; practice is key.
