HEADLIGHTS SEEMS TO BE PULSATING

1990 Honda Civic

Would this indicate that the alternator is on it's way out?

While driving the headlights and dashboard lights seems to be pulsating, especially when you come to a stop, then they're really bad.

At least yours just pulsate. I replaced an alternator and the headlights blew out. I think it had a bad regulator built in (inside the alternator). Prior to that it was the heater fan and headlights that were pulsating. I replaced the battery and alternator again, because the battery also fried from the surges.
