Re: smoking tail lights
Nightshades looks good from far. Meticulous prep, booth sprayed and they always have orange peel. Looing dead on is fine, but you see it at an angle.
Oracal makes transparent film for lights. I've done black, red (to make clear areas red), yellow headlights and more. Many color options. Google Oracal 8300. Amateur project if you're willing to waste some tries.
