The yellow colour of a foglamp is to reduce glare. The shorter wavelengths,
(on the violet end of the spectrum) which tend to be scattered more easily
by water particles suspended in air (which is, after all, what fog is) are
practically absent in the yellow light of foglamps. Since the amount of
scattering is a lot less for these longer wavelengths, less light tends to
be reflected back into the driver's eyes.

Maybe this should be in net.physics ...
