5% on a dark road or area, you really can't see anything at night. 20% is as dark as I would go, too dark of tint makes the car look like a G ride. Which is good......if your gangsta.
Very true. I'm thankful for the backup camera at night. And I have to be a bit more careful at intersections at night for pedestrians. Looking out the 20% sides is pretty dark. I was going to get 35 on the windshield but my tinter suggested doing 50. I'm glad I took his advice.
