Clear or Yellow Fog Lights

Q: Do yellow fog lights work better than clear ones?

A: Some people debate the answer to this one, with no clear cut conclusion. Some studies indicate that yellow fog lights do not offer any added visibility. Others will claim that the yellow wavelength is longer, causing it to cut through the fog better. The science behind this doesn’t necessarily agree. The key in getting the best visibility is less dependent on color and more dependent on being properly mounted and aimed.
