Picture yourself driving down a long, twisting mountain road in the late afternoon. You’ve been out all day – hiking, fishing, simply driving – but now a thick fog has rolled in over the landscape. You can count on your Ford Mustang Fog Light to keep you and your vehicle safe in the thickest of fogs.

A common characteristic of a fog light you might install on your Ford Mustang is its yellow color – perhaps surprising in a land of bright white headlights. The reason for this is related to the wavelengths of visible light as they scatter diffusely from the water droplets of the fog.

This phenomenon is called dispersion. Illuminated with only one color of light (and thus utilizing only one wavelength), objects seen through a fog will remain fuzzy and blurry because the fog is responsible for scattering the light. White light, normally used in standard headlights, is useless in fog because the many wavelengths (light colors) present in its makeup will disperse due to the water droplets, neutralizing the light’s effect. So what is a Ford Mustang Fog Light to do? Scientifically, a long wavelength is preferable, as it does not scatter as much as do short wavelengths. Yellow, in addition to being a color of light human eyes are particularly sensitive to, has a notably long wavelength and is thus the optimal color for a car’s fog light.Your Ford Mustang Fog Light, which is specific to the front driver’s side, front passenger’s side, rear driver’s side, or rear passenger’s side, is mounted near the vehicle’s other lighting fixtures.
