Not sure with that year of Packard, but if there is a self resetting breaker or self healing fuse, the could be weak and causing a cycleling when under the load of the headlights.

A multimeter with a amp settings might we useful to determine the load the headlights are putting on the system. The removing disconnecting the bulbs at their sockets and measueing the load again to see if there is anything else pulling a load.

And ohmeter can be useful with the battery disconnected and then it used with the to see where their is a path between ground and feed.

My battery was being drained and I couldn't figure out why as everything was off. By using a ohm meter I tracked it down to a sticky trunk light switch.
