What Causes Scattering in Headlights with Lenses?

[MacRiley]

Headlights with lenses scatter light because the bulb is not properly aligned. You can adjust the bulb's position vertically and horizontally. If scattering persists after adjustment, it may be due to poor lens quality, and you should promptly visit a professional repair shop for maintenance or replacement. Below is an introduction to the definition and function of headlight lenses: Definition of Headlight Lenses: A headlight lens is an optical glass lens installed in front of the headlight bulb. It helps focus the light, increasing the beam's range for better illumination, primarily used in xenon headlights. Function of Headlight Lenses: Xenon headlights produce bright but scattered light, which can dazzle other drivers. Lenses have strong light-focusing capabilities, gathering scattered light into more parallel beams, known as the focusing effect. After installing headlight lenses, the light will not scatter, improving ground illumination without affecting oncoming traffic, thereby enhancing driving safety.
