My 145K mile 2002 has the worst headlights I've seen on any Porsche. Very cloudy and yellow, and the lenses themselves have several burnt spots on them. I've tried sanding them and doing all the chemical treatments, but no luck, they were just too far gone. So I finally sprang for new ones!
I purchased these from a vendor on Amazon, and they were less expensive than any others that I could find when you factored in the free shipping.
The difference is amazing! I am no longer embarrassed when I see another Porsche!
I'll get rid of the amber triangle lenses. I ordered some clear triangles when I ordered the headlights, but they won't arrive for another few days.
