:fencelook: white light no matter what angles are bad for fog, the light refraction is off the moisture in the fog/air not from the fog light units
You're not following. If the beam is bad and sprays light upward instead of down. It causes more refraction in the fog and less visability. Regardless of colour this is going to make the biggest difference.

:thumbs: if you say so.
So does logic, science and the internet but you clearly know something I don't.
"Yellow Vs. White Fog Lights
A foggy roadway presents one of the most hazardous driving conditions out there. Fog is similar in its makeup to a cloud at ground level. Water vapor in the air condenses and forms suspended water droplets when the temperature reaches the dew point; the water droplets in the fog act as small mirrors, often reflecting the light of normal headlights back into the field of vision of drivers, making driving a real hazard.
How Fog Lights Work
Many lights are marketed as fog lights, but they are not all equally effective in helping a driver see in foggy conditions. The light pattern is what makes the difference in a good, effective fog light.
Fog lights should have a wide beam pattern of 70 to 120 degrees, with a flat cutoff on top to reduce the amount of light directed up into the fog and thereby reducing the reflection of that light into the driver’s field of vision.
No light can penetrate fog. Fog lights should be mounted and aimed to illuminate the road under the fog, which tends to drift a foot or so off the ground. Fog lights should be mounted at bumper lever or lower and aimed straight ahead or slightly down, to be most effective.
The Yellow Wavelength Fallacy
Each color in the light spectrum has a different wavelength. Air molecules scatter colors of shorter wavelengths more so than those of longer wavelengths. White light contains all colors, the argument has been made that yellow light, with a fairly long wavelength, will be less likely to be scattered. The problem with this argument is that the moisture droplets that make up fog are too large to selectively scatter different wavelengths of color.
This being the case, yellow light holds no advantage over white light."
Like I said the main issue with these bulbs being less effective in fog is the beam pattern. Similar to putting HID in halogen housings without projectors.
