Anyone else have this problem with Anzo USA Headlights?

I purchased a set of Anzo U-Bar style headlights about a year ago. After having them for a couple months, i noticed some sort of defect on the inside. Almost looks like mold but i don't think it is. Looks like the film on the inside is bubbling or something. I thought maybe when installing them they weren't sealed completely but that wasn't the case. Has anyone else had this problem with these headlights or any other headlights?

 

Did you put any silicone on the edges of the light when you got them. Just to make sure they was sealed? Thats the only thing i know of them. I had them on my f150 for a year and a half and no problems. Sold the truck so no idea now. The only time i have seen people with problems is when they did not silicone them.

 

That's got to be mold. I found something similar on another forum:

Thanks for the response guys. Judging by the picture @JdevTac provided, now i am thinking its mold.
