I am still leaning towards headlight tint as well, same thing, light tint for looks and protection. The headlights look great, no sense covering them in dark tint while probably making them dimmer at the same time. I have read a few stories about tint causing headlights to crack due to heat retention. I will defer to the tint experts at Shadow Tint when I bring it in.Not sure where you are located.
I had XPEL put on my Vette back in '15 by Touch of Tint . They were reasonable, but used the diecut pattern. I wished I'd gone with sekanskin.com they were going to do custom, but I got cold feet at the extra cost. They were going to remove the bumpers, mirrors and all emblems and trim. Wish I'd spent the extra 700. Now by the mirrors the slits are becoming more noticeable, also have a few nicks in the paint along the edges of the hood where the pattern just stops before the edge.
One cool thing Touch of Tint did was tint the headlights. They put a slight tint that makes the headlights blend into the car better and also adds some protection to the lens.
