What is a Headlight Lens?

[DeAvery]

A headlight lens is an optical glass lens assembly installed in front of the headlight bulb, which helps focus the light beam for increased projection distance and improved illumination. Below are specific details about lens installation: Lens Selection: Most aftermarket lenses can pass annual vehicle inspections as long as they don't impair lighting performance. Factory-equipped high-end models with lenses don't require registration modifications. Properly installed lenses effectively solve the issue of scattered light from stock headlights, significantly enhancing nighttime driving safety. Penalty Notice: According to Article 90 of the Road Traffic Safety Law, unauthorized installation of lenses or xenon headlights constitutes illegal vehicle modification violating safety standards, punishable by 3 penalty points.
