In states where salt is used liberally on the roads, it can help keep the lenses clean, and therefore light up the road up ahead nicely. Also, during those not so sunny daylight hours, other cars can spot your headlights easier when they are clean, vs. something that looks like a 25W lightbulb behind a window that hasn't been cleaned in 10 years.

Having said that, I am glad I don't live up there anymore.
