What is the standard distance for low beam cutoff line to the ground?
2 Answers
10 meters from the wall, the lower edge of the cutoff line is 0.875 meters from the ground. The relevant introduction of low beam is as follows: Combination methods of low beam: There are mainly two types of combination switch methods for car low beams, one is the lever type, located on the lever on the left side of the steering wheel; the other is the knob type, located below the left air vent on the center console. When to use low beam: When driving in areas without street lights at night, or when driving at dusk when it is relatively dark or at dawn when the light is just appearing, the low beam must be turned on; if encountering heavy fog, snow, or heavy rain, where visibility is obstructed, the low beam must be turned on even during the day; on some roads where there are lighting facilities but the brightness is insufficient, the low beam should also be turned on.
When talking about the cutoff standard for low-beam headlights, I remember it's about 50 meters on the ground. The key position where the beam cuts off that distinct line between light and dark helps avoid dazzling oncoming drivers at night while still maintaining good forward visibility. There might be slight variations depending on the vehicle's height—SUVs may have a slightly shorter cutoff, while sedans are more standard. After driving for over a decade, I've noticed that improperly adjusted headlights either illuminate too close (like driving blind) or shine too far (earning curses from others). Measuring it isn't hard: find a flat road at night, stand by the front of the car, and estimate where the beam sharply transitions to darkness—anywhere between 30 to 60 meters is normal. Beyond this range, it could indicate loose adjustment screws or suspension issues, requiring professional repair. Safety comes first—don’t recklessly tweak the angle just for lighting mods, or you might get pulled over by the police.
