If only the headlights are dull and not putting out the correct light, I would suspect a bad ground (earth) connection somewhere in the headlight circuit or the fuse for the headlight circuit. Something is causing excessive resistance and causing less voltage to be provided for the headlights. If all the lights are dimly lit, then I would check the charging system, the battery and the ground cable for the battery, chassis, and engine.
