Selective yellow illumination, produced by specialised lamps for antagonistic climate situations, enhances visibility by scattering lower than white mild in fog, rain, or snow. This attribute improves distinction and reduces the back-glare mirrored in direction of the driving force.
Improved visibility in difficult situations represents a major security benefit. The selective transmission properties of yellow mild reduce the “veiling luminance” impact the intense halo skilled when white mild displays off precipitation. Traditionally, yellow lamps have been favored in areas with frequent fog or snowfall, and their effectiveness has been supported by analysis into visible notion and atmospheric optics.
