What is the Difference Between Single-Lens and Dual-Lens Headlights?

There are the following differences between single-lens and dual-lens headlights in cars: 1. Functional scope differs: A single-lens headlight generally only covers either the low beam or high beam function individually, while a dual-lens headlight can integrate both low and high beam functions into a single lens. 2. Performance varies: The light cutoff line produced by a single-lens headlight is not as good as that of a dual-lens headlight, and the range and width of the light beam from a single-lens headlight are also inferior to those of a dual-lens headlight. The working principle of a dual-lens headlight involves receiving the headlight switching signal, activating the solenoid valve, and adjusting the angle of the lens to switch between low and high beam states. 3. Solenoid valve presence: A dual-lens headlight contains a solenoid valve, whereas a single-lens headlight does not.
