Actually, I could use some rear fog lights every now and then. Since there is limited visibility back there to begin with, coupled with dark window tinting and the fact that I live somewhere that we don't have many lights, sometimes it would be great to be able to turn some rear fog lights on so I could see what I'm backing into. Also, it could help with things like camping, or hooking up a trailer (for those who have a rear hitch).

But, it would definitely help when I'm hauling arse down the highway in reverse...those wimpy reverse lights simply do not throw enough light to scare the deer away.
