I personally would not go with 10%. Not only would it be very difficult to see out of at night, but it would be darker than the OEM tint thats on all the other windows. I see no reason to go with 10% film on the front windows. The best option that gives you a perfect match to OEM tint, still allows you see out at night without too much trouble, and looks amazing from the outside is 20%. This would be cheap as well since you only have to tint two windows. My tinter charged me $60 bucks for the front two windows. Looks incredible!
Here is my Overland with Saddle interior using 20% Llumar film on the front windows. Love it and would not recommend any other way!
