Well limo tint is one of the darkest, and you have to have a permit from a dr. or someone who has connections to *legally* have it.

Then there's 5%, 10%, and so on, with the higher the percent, the more amount of light gets through the tint. I think 5% is illegal in most states, but all the other ones should be good.

I say just get them like 5% at most, b/c that just gives cops another reason to pull you over..

OR, get a note signed from an eye doctor that your eyes are sensitive and you can legally have them dark. Lol, a lot of my friends have "sensitive eyes" I guess..
