Yellow fog lights not only allow you to see further during foggy weather but can also make you more visible to other motorists and road users, reducing the chances of accidents.
Yellow fog lights are specially made to help drivers navigate the road carefully in foggy conditions. Yellow lights are the best among fog light colors because they hit your retina in a way that enables you to focus on the road. Staring constantly at white light can frustrate the eye, and darker colors like blue and green have limited wavelength.
In addition, yellow fog lights penetrate foggy weather better than other light colors. Fog tends to reflect the color of the driver's lights directly in front of their eyes. Staring at white light is already a difficult task, and having the white color reflected close to your retina when you are driving might destabilize your focus. In the same way, looking closely at blue lights can make your sight fuzzy. Yellow lights are the only light color most drivers can withstand in the fog.
