Update - found out the intermittent lights was actually burnt filaments making on and off contact.
Got new bulbs and decided to check voltage at light connectors before installing. Had wonky readings - fractional voltage, and inconsistent. In my infinite wisdom, I decided it must just be a bad meter connection, and at least the voltage was low so I would not blow any bulbs. I decided to install the tail light bulb to check. It lit up - ran at idle and no issue. Once again, because I am so smart I decided everything was good and went ahead and installed my nice new xenon headlight. It lit up beautifully, then I revved up the engine and blew both bulbs.
Then figured out voltage regulator must be shot. Then my own light bulb went on in my head - re checked for AC voltage. Bingo -. About 12 volts at idle, over 40 volts when revved.
Lesson learned - and shared. Trust your meter, and remember lighting coil produces AC voltage until rectified.
Regulator and new bulbs ordered!
