Default 1974 left headlight trouble

I have a situation where my 1974 left headlight pops up without turning on the headlights. All I have to do is start the engine. It used to go down after a second or two but now it has progressively stayed up longer and longer until now when I start the engine that left headlight just pops up and stays. It eventually goes down while I am driving and when she feels like it. Can you diagnose the culprit from this description?

Default Hi and welcome!

Your '74 should have two relays and the left one may be bad.
Here's how to test all the parts:
