What is the difference between car lights with and without lenses?

[Wright]

Car lights with and without lenses have the following differences: Difference one: Lights without lenses have a more scattered effect and are more glaring, which can affect the driver's visual experience. Lights with lenses can focus the light, achieving the best illumination effect. Difference two: Under the same light source, lights with lenses have an illumination distance, width, and brightness that are 3-5 times greater than those without lenses. Lights without lenses have limited illumination distance and width, posing a safety hazard while driving. Difference three: Generally, low beams are equipped with lenses, while high beams are not. The reason is that low beams are most commonly used in urban roads, whereas high beams are rarely used.
