Just reflection from the flash, they're quite large flat pieces.  Been on the car over a year now and it's still intact.

They do it in different colours, some refer to it as gold and others places yellow.  But they're the same finish.

This is where I had my parts done

Won't be local to you but it gives you an idea of what is available.  I'd collect a bunch of other items together so you get better value for money, the place I took mine kinda charge per box full irrespective of what's in there.
