How to Use Headlights When Meeting Another Vehicle?

When meeting another vehicle at night, it is essential to turn on the low beam. If the high beam was previously on, be sure to switch back to the low beam in advance. After the vehicles have passed each other, decide whether to turn on the high beam again based on the road conditions. During the meeting, quickly switching between high and low beams can alert the other driver. If the other vehicle uses the high beam, it may impair visibility of the road.

I just completed a long-distance night drive last month and deeply realized: the proper time to switch to low beams is about 150 meters before meeting oncoming traffic. When you spot headlights from an approaching vehicle - regardless of whether they're using high beams - immediately switching to low beams is fundamental driving etiquette. If the other driver forgets to dim their lights, don't stubbornly keep yours on high either - slowing down slightly can help prevent being blinded by their brights. Especially on mountain road curves, switch to low beams before entering the turn to avoid dazzling others. When encountering persistently unreasonable drivers who won't dim their lights, just flash your high beams twice as a reminder - never engage in a high beam standoff, safety always comes first. On well-lit urban roads, you can simply keep low beams on without constant switching.

We veteran drivers often drive at night and find it most annoying when oncoming vehicles keep their high beams on. Remember this golden rule: the moment you see headlights ahead—whether from a car, motorcycle, or electric bike—immediately switch to low beams! The safest distance to switch is around 150 meters. The key is to develop muscle memory: keep your left hand near the light stalk, and instinctively switch back to low beams when you spot headlights. A blue indicator on the dashboard means the high beams are on. If you're on an unlit road and the oncoming vehicle hasn’t dimmed their lights, you can flash yours twice as a reminder. Avoid prolonged high-beam flashing—it’s both provocative and dangerous. If you encounter a newbie who forgets to turn off their high beams, be patient, stay calm, and drive past slowly.

Over the years of car light modifications, I've noticed that many people actually don't know how to use high beams correctly. There are two key points when meeting oncoming traffic: turn off high beams in advance and judge the distance accurately. Generally, you can spot opposing headlights from 200 meters away - that's when you should start decelerating, and must switch to low beams within 150 meters. Those who've installed powerful LED or laser headlights need to be extra cautious - the brighter your lights, the sooner you must dim them, or you'll genuinely blind oncoming drivers. Proactively slowing down and switching lights before narrow roads or curves is safer. In heavy fog, avoid flashing high beams as the whiteout makes visibility worse. Fun fact: When driving night routes in Norway, you might encounter just a few cars all night, making these skills practically unnecessary.
