What number should the low beam 123 be adjusted to?
2 Answers
There are no strict regulations on what number the low beam should be adjusted to. The smaller the number, the higher the beam height. The following situations require the use of low beams: 1. Driving in areas without streetlights at night, during dusk when it's dark, or at dawn when light is just appearing. 2. During heavy fog, snow, or heavy rain when visibility is poor, even during the day. 3. On some roads where there is lighting but the brightness is insufficient. Additional information: Low beams are designed for close-range illumination, with a wide coverage angle (160°) and short projection distance, and the focus cannot be adjusted.
I've been driving for decades, and adjusting the low beam height is a basic skill. The 1-2-3 dial is usually located on the lower left side of the dashboard near the steering wheel. Number 1 indicates the highest beam position, 2 is medium, and 3 is the lowest. When the vehicle is unloaded, setting it to 2 is most appropriate - the light will illuminate 40-50 meters ahead without dazzling oncoming traffic while ensuring good visibility. If your car is fully loaded causing the front to tilt upward, set it to 3 to prevent the beams from pointing too high. Regularly check this setting, especially after seasonal changes or long trips, to prevent nighttime hazards. Never leave it permanently on position 1 - those upward-pointing beams can dangerously blind oncoming drivers. Simply turn the dial while parked to test adjustments - it's quick and safe.
