Open the engine compartment cover, locate the rear cover of the headlight at the headlight position, unplug the connector, and unscrew the bulb. More related information is as follows: 1. The low beam headlight is designed for close-range illumination, with a large coverage area (160°) and a short illumination distance, and the focus cannot be adjusted. The low beam must be turned on in the following situations: driving in areas without streetlights at night, driving at dusk when it is relatively dark or at dawn when the light is just appearing; if encountering heavy fog, snow, or heavy rain that obstructs visibility, 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. 2. Although the low beam has an illumination distance of about 30 meters, it has a very noticeable beam cutoff line. Most car low beams have an illumination distance of 30-40 meters, with the beam cutoff line at about 12-18 meters. The area in front of the beam cutoff line is brightly lit, allowing clear identification of objects, and a clearly visible illuminated area of 2-3 meters in diameter can be seen on the ground. The area from behind the beam cutoff line to 30-40 meters mainly relies on ground-reflected light sources. In this area, brightly colored objects can be distinguished, but dark-colored stationary objects on the road are not easily noticeable.
