I have vinyl on my 3rd brake light on my 2006 and have no issues with it. It was DieCut to fit, but I did leave a little extra to completely cover the entire light, even on the sides or lip as much as possible.
Vinyl is cheap and replaceable and or removable if you don't like it, where most other options for doing what you are wanting are not.
I would go with the vinyl. Its easy to undo just peel it off. I had black out on my 06 tail lights. takes a little heat but looks pretty good in the long run. I did try night shades on other lenes and found it hard to get a consistant "tint"
