What Are Low Beam and High Beam Headlights?

[LeCharles]

1. Low Beam Headlights: Low beam headlights are designed for short-distance illumination. The design requirements include a wide coverage area but a short illumination distance, with non-adjustable focus. The illumination distance of low beam headlights is approximately 30 to 40 meters. The light emitted beyond their focal point is divergent, providing a wide coverage area despite the short distance. 2. High Beam Headlights: High beam headlights achieve the effect of increasing the driver's visibility distance by projecting brighter light (some models use the same bulb for both high and low beams, achieving the difference through light shield adjustments) directly in front of the vehicle. Generally, low beam headlights can cover up to fifty meters ahead of the vehicle, while high beams can reach hundreds of meters or even farther.
