If you go with the perforated vinyl it would be little considering it has holes in the vinyl to allow for light to shine thru, or to allow you to see out since its commonly used for windows on full vehicle wraps. In this case it should be far more visible than if you tinted the bar. But like I said, If it was me, I would cover the reverse bar (only need light to shine thru when your backing up, and the white light would shine thru easily) and the 3rd brake light, if its visibility is reduced o well, you have the mains on anyways. The cut outs on these I actually do like, but I would leave it like that, cut out, so its visible when your braking.
