Can you see led lights in foggy days?

In rainy and foggy days, led is not easy to use, because the light wavelength of this lamp is long wave. In the case of rain and fog in the air, the light cannot be refracted and the penetration is reduced. The light of yellow light (fog light) is short wave, which can be refracted in foggy and rainy days. To put it simply, all car emergency lights in the world use yellow lights, because in bad extreme weather, yellow lights have the strongest penetration.

Car headlights are car headlights. Headlights are lights symmetrically installed on both sides of the front end of the vehicle, which are used to identify the front horizon when driving at night. LED is an electroluminescent device, which uses solid semiconductor chips as luminescent materials and emits light directly through photon emission caused by carrier recombination. LED headlights are lighting appliances made of LED as light source.

Vehicle rear fog lamp refers to a red signal lamp installed at the rear of the vehicle in low visibility environment such as fog, rain or dust, which makes it easy for other road traffic participants behind the vehicle to find, and its luminous intensity is greater than that of the taillight.
