Hi,my name is mike and I will assist you with your question.
From what you are describing the vehicle voltage is under charging and resulting in the issue that you are having. It does not sound like the alternator has failed but the alternator is starting to get weak which is where the battery light comes from. As a first step the alternator needs to be load tested and the battery tested as well.
