 og> Has the "fogging" been fixed?  If so, what year do they start showing up?

I doubt it.  UV light is pretty brutal stuff and tends to degrade plastic over time.  The UV resistance of headlight plastic has gotten MUCH better over the years, but I wouldn't call headlights "UV-Proof" by any stretch.

The newest vehicle I can recall doing a headlight restore on was a 2017 F550, about a year ago.  That's about the amount of time that it takes for OEM new headlights to get foggy enough to need restoration.

I'm sure that the plastics engineers are continuing to improve UV resistance.... I only wish we could mold glass the same way we mold plastics. My glass headlights never needed this kind of treatment.
