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.
When I bought a Mercedes last year, the salesperson explained the headlight technology in detail. Now, all Mercedes models come standard with LED lenses. On the surface, the lens looks like a piece of transparent glass, but inside, it has precise reflective surfaces and convex lens elements. For example, my GLC uses a single lens paired with multiple LED bulbs, while the EQS electric car in the showroom is equipped with a 1.3 million-pixel digital lens that can project patterns onto the road. I recommend paying attention to the lens type when choosing a car. Those with blue decorative rings are high-end Multibeam LED headlights, which automatically provide additional lighting when turning at night. The difference is quite noticeable when driving in the rain, as the lens beam doesn't scatter like light from reflector bowls would in foggy conditions.
