Headline covers clouding over

I had reason to change one of my headlamps on a 2002 Clio. I was astonished at the difference bewteen the two as thge old one had browned. I believe the Clios have styrene covers and not acrylic. I have experience of using both in framing, and styrene always browns with UV light, unlike acrylic.

What do you think?
