Take it to Advance or AZ and have them test it. The machine they have tests the battery and runs some load tests on the alternator. You'll know what's wrong in 2 minutes.
I had this same problem. The alt. was putting out about 40 amps, way too low The brushes in the alt were shot. New brushes, no more dim lights.
BTW, removal of the alt. on a Duratec is a major pain.
