Headlight cracking on its own?

its definetely the plastic getting cooked...cheap crap.

 

Rice plastic. Look it up.

 

Here is a interesting article on plastic vs. glass headlights.

I don’t have cracking but I have this which looks like moisture build up. I noticed it about 15,000 miles ago but haven’t paid much attention to it but it’s been getting bigger slightly over time. I’m at 29,000 miles now so I’m going to take it in before my bumper to bumper warranty runs out.

 

I’ll have to check my headlights, some stuff I write off as that’s normal without even knowing it was a thing

 

Dealer cannot do anything as I am outside the factory warranty and Toyota Corp's extended warranty does not cover headlight housings. Of course, lol, I suppose when it gets real bad I may have to attempt to black out my housing guts and play with the stove!
