Why do my head lights dim when my brakes are applied?
More than likely your alternator is faulty. The alternator is supposed to charge the battery and run the car's electrical system when the engine is running. If your headlights dim it means that not enough electricity is being provided. A simple free test at just about any auto mechanic shop should confirm if the alternator is faulty. If the alternator is faulty, and it is not just due to a loose belt, you want to replace the alternator as soon as possible. Eventually it will fail to charge the battery, and you car won't start.
