I have seen quite a few tail lights red-out tint on this forum, but haven't seen any headlight smoke tint.

www.rvinyl.com has both. The installation shows the difficulty level is 4 of 5 for the headlights and 3 of 5 for the tails. I went to feel the headlights and there seem to be some weird curves, like the surface has some ups and downs.

The tails are smoother in curvature in comparison. Has anyone done the DIY installation? How difficult is it? Does it require professional installation.
