[0002] The core of car headlights is mainly the use of dual-beam lenses. Dual-beam lenses are mostly used for xenon headlights that share the same light source for low and high beams. There is a shading plate inside the lens, and the high and low beams are achieved by moving the shading plate up and down. In this way, only one xenon bulb is needed to switch between low and high beams. Dual-beam lens: It is a lens.
