Vvivid vinyl air tint smoke headlight tint. Did the rear cabin light, mirror turn signals and headlights. Very easy to work with, but I really have no basis for a comparison because this was my first experience w vinyl or tint. This color (smoke) barely affects light production and still lets you see those beautiful LEDs in the right light.
Check out CK Wraps on YouTube, he swears by this stuff and convinced me to use it. He has a video where he does an f-150 headlight and shows the negligible difference in light production between tinted and not.
Did you think about trying on Rear Brake lights?
I gave it a try (also first try at anything like this) and struggled. I think the Rear park Senors built into tailights makes off not smooth shape. I tried cutting out didn't look good. At the end I got frustrated and ripped it off. I may try the same lights at you, they look nice and flat.
