My battery light comes on and off intermittently. The battery checked out OK. on 1999 Ford Ranger

Just started today. On for 5 miles, off for a few more, back on again, all while driving. Dash lights seem to be fading also. Any idea of cost for parts & labor if it is alternator? Thanks all!

Sounds like the alternator only works part of the time.
