yesterday I saw a car with "windshield wipers" on the lights. I had never seen this before, and honestly, I'm not sure I understand the use...I mean, the heat of the lights should take care of melting any snow that hits when driving right?
Clearly, you don't live in Montana.
Snow aside, even on highways (not to mention unpaved roads, which really do exist some places without resorting to driving through the forest) there can be enough dust and dirt building up that it effectively dims the lights.
I grew up on unpaved roads.

Never had that much of a problem with my headlights dimming from the dust, but I probably just never noticed since they liked to randomly stop working on my cruddy old car anyway. ^_- There's nothing like
that occurring when you're in the middle of nowhere when driving home from watching a scary movie.
Personally, I rather think DVD players in vehicles are a bit pointless, but I tend to think people spend too much time in front of the tv anyway (myself included). Plus, the ones that aren't actually built in can become dangerous projectiles not just during crashes, but also when maneuvering to avoid a crash.
