Answer
Ola,

You will need to have the electrical system checked.  It sounds like the alternator is going out.  The battery light shows, not only the battery, but the state of the electrical system.  And, in your case, the alternator is probably not putting out enough voltage to keep the battery charged and the electrical system fully powered.
