What is the difference between Xingrui headlight lens and ordinary ones?

[VanBradley]

The differences between ordinary headlights and lens headlights are: 1. In terms of brightness comparison: Lens headlights are generally used in xenon headlights. Compared with ordinary headlights, a set of lens system is added in front of the bulb, which is brighter than ordinary headlights. 2. In terms of illumination principle and lighting efficiency: The light of ordinary headlights is directly emitted by the bulb and the rear reflector bowl projects light forward, resulting in significant scattering and waste of light. The lens can change most of the light scattered by the bulb, effectively focusing the light (similar to the principle of a magnifying glass), thereby improving the efficiency of road lighting.
