Are Small Lights the Same as Low Beam Headlights?
1 Answers
Small lights refer to low beam headlights. Large lights refer to high beam headlights. Low beam headlights are designed for close-range illumination, with the design requirements focusing on a wide coverage angle (160 degrees), short illumination distance, and non-adjustable focus. High beam headlights emit parallel light, which is more concentrated and brighter, capable of illuminating distant and high objects, thereby improving visibility and expanding the field of view. When to use low beam headlights: When driving in areas without streetlights at night, during dusk when it's getting dark, or at dawn when light is just appearing, it is mandatory to turn on the low beam headlights; if encountering heavy fog, snow, or heavy rain that limits visibility, low beam headlights must be used even during the day; in some areas where lighting is available but insufficient, low beam headlights should also be activated. Function of low beam headlights: Although low beam headlights have an illumination distance of about 30 meters, they feature a very distinct beam cutoff line. Most car low beam headlights illuminate between 30-40 meters, with the beam cutoff line appearing around 12-18 meters. The area in front of the beam cutoff line is brightly lit, allowing clear object identification, and the ground illuminated by low beam headlights typically shows a visible light area of 2-3 meters in diameter.
