Yellow/Brown marks in Headlight projections

[preeman]

Hi Guys,
Can I please get some photos of the headlights in your Scirocco, I have started to notice that there are yellow/brown circles in the projection throw.

Could it be that the internal lenses are developing marks? Or could it be that the internal projection holders are getting marked by their own heat?

I don't remember seeing these brown marks when I had the car at the start.

Should I expect this to keep getting worse and the dark spots in the projection to keep growing? If this keeps growing my headlight throw/coverage is negatively effected.

What are your thoughts? Pictures to compare would be great.
