if your alternator was bad your battery light would come on
batteries can become weak, but if the car cranks over nicely and fires up fine then i wouldnt worry about it

my car with the lights on, on the highway at revs, when i roll up windows makes my lights flicker, these alternators probably dont put out that much amperage, thats all

your miss is something else, and it is a horrible idea to diagnose problems just on gut descions and/or guessing, if you are worried about it and are that unsure i would say take it to somewhere knowledgable and see what they say
