Dim headlights, a battery warning light or a battery that keeps running down can mean the alternator is not charging as it should. Before you replace the alternator, rule out a slipping belt, loose or corroded battery cables and a worn-out battery, since each can look the same from the driver's seat. A shop can load-test the charging system.
