I need both tail light bezels. Where can I find those for a decent/reasonable price? Perhaps, does anyone have a set they could let go of?

 

Do you mean the chrome, (sometimes black) pieces that surround the lens ? If so, then they are not separately supplied by Jaguar, it the whole rear light assembly or nothing.

Adamesh do some chrome fittings that stick over the top of the bezel and are a bit wider. I have fitted them on my car, as well as a chrome bootlid plinth, to replace the bodycolour one the car came with (it's a Sport).
