Miata Popup Headlight goes crazy

[BRGNA8]

Hey guys

Ive noticed that sometimes (quite often now) that my right pop up headlight wont behave as its meant to. I'll press the popup button or turn the headlights on to pop them up, and that's fine. It's when I try and retract them back down that the right one just goes crazy.

It will just flip up and down numerous times before finally settling down and retracting back on its own accord

Ive attached a youtube clip of it going crazy.

Any idea what the issue could be? Retractor rods? Fuse?
