When to Use High Beam and Low Beam Headlights?

[DiPaige]

When overtaking, turn on the left turn signal in advance and switch between high and low beams; at night, when driving on sharp curves, slopes, arch bridges, crosswalks, and other sections of the road, alternately use high and low beams. Below is relevant information about high and low beam headlights: 1. Purpose: High beam headlights are suitable for driving at night on roads without street lights or with poor lighting, such as on dimly lit national highways or expressways. Low beam headlights are suitable for roads where oncoming vehicles are within 150 meters. 2. Speed: When driving on the road, the speed should be below 30 km/h when using low beams and above 30 km/h when using high beams.

As someone who often drives at night, I find the use of low and high beams simple yet crucial. Low beams are used in urban areas with streetlights, during rainy or foggy weather, and when encountering oncoming or preceding vehicles, as these conditions reduce light scattering and improve road visibility. High beams are suitable for unlit suburban roads, highways, or open rural areas when visibility is clear and no other vehicles are present. I remember once driving with high beams in the rain, which made it harder to see ahead due to the intense reflection off the raindrops; the same goes for foggy conditions, where high beams create a blinding whiteout. However, as soon as you spot oncoming headlights or taillights, you must immediately switch back to low beams to avoid dazzling others. Safety comes first—never forget to switch beams promptly, or you risk accidents or fines. Make it a habit to check if your lights are functioning properly before setting off, and replace aging bulbs in time.

When I first got my driver's license, my instructor repeatedly taught me the rules for using car lights, and looking back now, it left a deep impression. In the city, always use low beams, especially when there are many cars to avoid dazzling others; high beams are only for remote roads with no traffic, like driving in the suburbs late at night, but switch to low beams immediately when you see oncoming headlights or the taillights of the car in front. Never use high beams in fog or rain because the reflected light can blur your vision, making it very dangerous. The regulations emphasize that misuse may result in penalty points, so I strictly adhere to them, and it has become second nature after forming the habit. Regularly checking the lighting system is essential—if the bulbs are not bright enough or the wiring is aging, it can affect the switching speed.

Having focused on road safety for years, I emphasize the correct use of high and low beams to prevent accidents. Low beams are the standard choice for nighttime city driving or when encountering oncoming traffic, while high beams are restricted to open, vehicle-free roads but must be promptly switched. Misuse of high beams poses a high risk of glare, potentially leading to collisions; they are prohibited in rainy or foggy conditions to avoid intensified light that impairs visibility. Adhering to traffic rules is a responsibility to safeguard both oneself and others. Ensure your lights remain bright and functional, and replace bulbs promptly if they appear dim or weak.
