Default Battery Light Beeping

My battery light came on and a strange new beeping sounds at start and then again after running for awhile. I saw somewhere it could be because my airbag light is burnt out. If so how do I replace it or disable it?

The battery light only comes on when the key is in the ON position and the alternator is not generating power. If the alternator isn't generating power, it is because either it isn't spinning or it is just toast. Either way, you're running only on the battery which is being drained everytime you start the truck and for the entire duration you have the key on. You should have the alternator tested and if needed, replace it quickly or you're going to be dead on the side of the road.

The air bag light and the SRS system have nothing to do with the battery light. They happen to be on the same fuse, but if that fuse was blown the light wouldn't be on.
