    Questions about headlights. I parked my '02 for a couple days and was leaving the house and noticed the headlights were on though the light switch was off. I started the truck, turned the headlights on the off and they go out. When I went to start it the next day the battery didn't have the power to crank it and it is beeping at me from the area of the fuse panel. I pulled the headlight relay, charged the battery but it still is beeping at me and the dash lights flash on and off with the beep. Since the headlight relay is out what else could it be?
