What kind of lens is used in Mercedes headlights?

Mercedes headlights use a combination of high and low beam lens on the outer side, and a separate high beam lens on the inner side. Automotive lens: Automotive lens are mainly used for xenon headlights. The headlight lens is a set of optical glass lenses added in front of the headlight bulb, which can focus the light more effectively, extend the illumination range, and achieve better lighting performance. The function of automotive headlight lens: Since xenon lights have high brightness but scattered light that can easily dazzle other drivers during driving, the lens has strong light-gathering capability. Its function is to gather the scattered light into more parallel beams, known as the light-gathering effect. After installing automotive headlight lens, the headlight beams will not diverge, providing better ground illumination without affecting the normal driving of oncoming vehicles, making driving safer.
Having repaired Mercedes-Benz vehicles for over a decade, I've noticed their headlight lenses are exceptionally sophisticated. Current mainstream Mercedes models predominantly use LED projection lenses that precisely direct light onto the road. Models like the C-Class and E-Class feature a single large lens paired with auxiliary reflector bowls, while premium vehicles such as the S-Class and GLS are equipped with dual-lens modules. What amazed me most are the AMG models, which utilize laser-assisted lenses capable of illuminating distances over 600 meters. Special care is required when servicing these lens modules - not only are they labor-intensive to disassemble, but a single OEM lens can cost over ten thousand yuan. I'd advise owners to avoid directing high-pressure water jets at the lens seams during car washes, as this can easily cause fogging or water ingress.
