Osram MK7 headlight housings - interested?

[RIP TDI]

Any clue what causes this reflection phenomenon on the lens? It's more easily visible when just standing in front of and looking down at it. I thought it might have to do with having 14-mil paint protection film on the lens but I confirmed the same effect with another Osram owner who had no PPF on his. It doesn't cause a problem, I'm just curious about what causes it and whether or not this is, in general, a common issue with 6000K projector LEDs shining through compound-curved polycarbonate lenses.

Not sure if it's a reflection, or a purposeful direction of light, otherwise known as "squirrel finders."

Anyone had issues with the lens coating starting to peel off? Just noticed it this afternoon. On one headlight the coating is starting to peel on the slightly exposed black surface above the lens, and the other is actually peeling on the top of the lens itself. Supposedly these things have a 2 year warranty, and I'm 23 months into owning this pair.

Oh shit, I didn't realize there was another Osram thread. Thanks for the link.

I'll take a look today.

I know this is like two years old, but mine have the same reflection pattern in the lens. Never had PPF installed until a few weeks ago after years of road use.

OK, so the reflection pattern only appeared after installing the PPF? If so, is it possible it was there before the PPF but your attention wasn't drawn to it until seeing these posts?

Sorry I wasn't clear, mine had this pattern since day 1 without PPF. Remained unchanged when I put PPF on.

Mine has this pattern, presumably from day 1, but confirmed when it was brought up in this thread. No PPF on mine.
