I remember some kind of study around yellow light being ideal for roads actually. The human eye is more sensitive in the green/yellow part of the spectrum, the lights are more efficient and cut through fog better.
- rootusrootus 3y agoThe difference between white & yellow light in fog is minimal. What really makes fog lights effective is being under 18 inches off the ground so they shine under the fog.

- ricardobeat 3y agoWhite light scatters more since it contains multiple wavelengths, generating more glare and losing brightness faster. And this is about street lighting, a 10% difference in brightness can result in massive energy savings.
