What is the function of automotive lenses?

[VanChristian]

Automotive lenses have a strong light-gathering capability, similar to a magnifying glass, which can concentrate the light and project it further. The classification of automotive lenses is as follows: Single-beam halogen lens: Single-beam lenses are designed with corresponding lenses for low beam and high beam separately. The difference with bi-xenon lenses is that they can switch between high and low beam functions, usually in the low beam state. Bi-xenon lens: These lenses are suitable for xenon bulbs and are commonly used in xenon headlights where the same light source is shared between low and high beams. Inside the lens, there is a shutter that moves up and down to switch between low and high beams. Common bi-xenon lenses include Q5, Hella 3, Hella 5, and Hella 6.
