A low fuel light saved my butt once (on another car). I was driving back from school to home for Xmas break (700 miles) and had been to a fraternity brother's wedding the night before. As you can imagine, I was quite hung over. I felt horrible, and my brain, malfunctioning as it was, decided that the more I drove the sooner I would be home. I was so dehydrated that bathroom beaks were unnecessary. Of course, I forgot that I couldn't make the drive on one tank of gas. I was in western PA, wayyy out in the boonies, in the middle of a snowfall when the light popped on. Good luck for me it was only 5 miles to the next exit, or I would have been walking for quite a while once the tank ran dry. If it wasn't for that light, I never would have glanced at my fuel gauge (which was in the middle of the dash on my 88 Trooper - horrible location) until I was trying to figure out why the truck was stalling out.
