Which setting of the low beam 0123 projects the farthest?

Among the low beam settings 0123, setting 3 projects the farthest. Precautions for using turn signals: When a motor vehicle passes through an intersection controlled by traffic signals and turns left or right, the corresponding turn signal should be activated. Precautions for using low and high beams: Low beams should be used when driving at night; when meeting non-motor vehicles on narrow roads or bridges, low beams should be used; high beams should not be used when a following vehicle is driving close to the vehicle in front in the same direction; when a motor vehicle passes through sharp curves, slopes, arched bridges, crosswalks, or intersections without traffic signal control at night, it should alternately use high and low beams to signal.

I've been driving for over a decade. The 0123 adjustment for low beams mainly controls the beam height, not brightness but rather the height direction. The 0 setting adjusts the lights to their highest position with the steepest angle, allowing them to shine the farthest and giving better visibility at night. The 1 setting is slightly lower, reducing the range a bit but making it more stable. Settings 2 and 3 are even lower, suitable when the car is fully loaded with passengers or luggage to avoid blinding oncoming traffic. I often use the 0 setting on highways when the car is empty—it feels like it illuminates an extra dozen meters, which is quite helpful. However, don't always use the highest setting; if the road is uneven or you encounter other vehicles, the strong glare can be dangerous. With more driving experience, you'll learn to try different settings a few times to find the right one. Remember to check the headlights regularly to ensure dust doesn't block them and affect performance. Safety first!

From an automotive perspective, the 0123 low beam adjustment knob controls the beam height. A lower number indicates a higher position setting, with the 0 setting raising the headlight to its highest point, resulting in a more direct projection angle and naturally the longest throw. I've inspected many vehicles, both new and old, and found that at the 0 setting, the beam can extend over 60 meters, while the 1 setting reduces it to around 50 meters. The principle is simple: a higher lamp angle allows light to reach further ahead. However, this doesn't mean you should always use the 0 setting—if the rear of the vehicle is heavily loaded, causing the center of gravity to drop (like when carrying cargo), the headlights may aim too high and need downward adjustment to avoid dazzling other drivers. It's best to manually adjust based on whether your vehicle is empty or loaded during daily driving to prevent issues. Regular maintenance of the lighting system is also crucial—clean off dust to ensure the lens remains clear.

Simply put, among the 0-1-2-3 settings for low beam headlights, setting 0 provides the longest illumination range. When turned to 0, the headlight angle is adjusted higher, projecting light further forward for better nighttime visibility. Setting 1 offers slightly shorter range, while settings 2 and 3 provide progressively lower and shorter illumination. Avoid always using the maximum 0 setting as excessive height can dazzle other drivers, creating safety hazards. Based on my experience, use 0 for clear road conditions and lower settings when encountering traffic. It's convenient and practical, even beginners can easily master it.
