My headlight lenses are pretty clear, but have yellowing around the corners. Is there a fix for that, or it is what it is now

 

You'll basically have to do some sanding and polishing and protecting at this point. There are numerous kits aimed at fixing this, some even include what is essentially a clear coat. They are all temporary fixes.

Replacing the headlights is the best way to "fix" the issue, at least in my experience.

Others with more professional detailing experience might have some long term solutions if there are any. I'd check in that area.

 

Thanks for the reply. I'm not sure if those will work for my problem though, as my lenses aren't hazey or yellow on the outside or anything. This seems more like the plastic itself is turning yellow, just in the edges. It only shows when the headlights are on. Idk, might be worth a shot though...
