If my Camry's OEM glass is 70%(visible light), what happens when I add 50% tint?

[bluemoose]

I was looking at the Toyota data for the '07 Camry's window glass. It said the visible light penetration rate is 70%.

If I were to add 50% window tint to that, does that equal 35%? (half of the original 70%)

The reason I'm asking is that my state's tint laws only allows 50% tint, but it doesn't say
if that's just for the tint film itself, or the tint film and OEM glass combined.

Thanks in advance for any advice!

If the tint shop is openly advertising their tint, and you ask these quesions of them they are likely to give you good answers. Also a call to the state office the oversees this could also answer, but anyway, 50% of 30% is 15% tacked back on to 70% is 85% in theory, right? Be careful trying to drive at night.

i think u are misunderstood, gdanaher.. if the window is OEM 70% VLT(visual light transmission), that means that 70% of the light shines through. if you add 50% VLT to that, in theory that will yield 35%(70/2).

yeah but the camry doesn't come tinted from the factory, so those figures are kind of arbitrary... a 50% tint is barely noticeable... personally i wouldn't get any less than a 30% tint, cause you wanna darken the windows somewhat.... i know i have a 20% tint on my car, and you can still somewhat see through the windows from the outside...

20% is where its at. you can still see through it okay at night and its fairly dark. people like picking 35% but i think thats way too light.

20% is perfect i have it
