maybe i'm wrong here, but my understanding is that the 07 ones dont just come off like covers as the 05/06 ones do. I think they are sealed, and you'd have to break the seal/glue...I think. How were these tinted? Is it a film?
i'm pretty sure the '05s have to have their glue seams cut as well. There is a pretty cool procedure involving a bench vise holding a utility knife blade...in one of the "headlight buffing the cover/restoration" threads. You hold the headlight assembly in your hands and drag the headlight cover seam over the blade. Works very well i hear.
