Replacing Fog Lights - Pure White Light

[Dose Pipe Sutututu]

Apparently the yellowish colour helps to cut through the fog a bit better but that is a rarity where I live.

More so others can see you better, notice on a foggy day you generally notice the cars with warmer tungsten headlights than once with HID/LED headlights? This is because during the day, fog actually appears quite white and projecting white lights through a white fog makes it harder for others to see/notice you.

From a driver's perspective any light frequency will just behave the same in terms of "penetration" as he wavelength is much smaller than the fog particles themselves.
