Outer Limits 4x4 Board

This morning as I was driving to work all of the warning lights started flashing on and off in no real set pattern. I was low on fuel and was going to call in and get some diesel anyway but when I did the lights stopped flashing. Is this some sort of warning that I'm just about out of fuel or could it be something else?

check your fuel filter for water as there is a sensor on the diesel fuel filter

Your alternator brushes are about had it. Fairly easy to fix.
