Can LED headlights be installed without lenses?

[WyattDella]

LEDs and lenses need to be installed together. Without a lens, the light scattering will be severe, which actually reduces the visibility of the LED. Therefore, when installing LED lights, a lens must also be installed. LED bulbs have good light concentration, and the light-shielding plate inside the lens is used to switch between high and low beams. The light pattern produced by a bi-xenon lens naturally forms a low beam with a clear cutoff line. However, without a lens, the light-shielding plate is absent, preventing the LED bulb's light concentration from being fully utilized, resulting in light scattering. Automotive lenses are divided into two types: 1. Single-beam lens: Only has a low beam, using halogen or xenon bulbs. 2. Bi-xenon lens: Achieves switching between high and low beams through an internal light-shielding plate. When the light-shielding plate is closed, it is the low beam; when opened, it is the high beam. If the bulb inside the lens remains unchanged, there will be no variation.
