This morning when I turned on my running lights (right after starting the engine) I noticed that they were flickering along with my instrument lights.

The car ran as normal and after driving for a few miles the flckering settled down and went away.

The car is a 71 daily driver with no previous issues like this.

I have a new alternator and new battery.

Any ideas?

Thanks.

The alternator might have a bad diode.

My guess would be the voltage regulator playing up.
