Why are LED headlights hard to see in the rain?

[JuliannaLynn]

Automotive LED headlights being difficult to see in the rain is due to color temperature. In rainy and foggy weather, the lower the color temperature, the better the penetration. The color temperatures of red, orange, yellow, green, blue, indigo, and violet increase sequentially, resulting in progressively worse penetration. In rainy and foggy conditions, this can lead to a situation where the road ahead appears hazy and unclear. White light is roughly positioned between green and blue, meaning white automotive headlights generally have average penetration. The solution to LED headlights being hard to see in the rain is: you can use the vehicle's fog lights for driving. Because fog lights have certain penetration in the rain and can also provide adequate illumination, using fog lights in rainy and foggy conditions is safer.
