Tint is our lightest film that blocks only 5% of light
Gunsmoke is our medium film that blocks 12% of light
Smoke is our medium-dark film that blocks 17% of light
Charcoal is our black-out film that blocks 30% of light
In that case, I can get tint on the brake lights and I guess i'll do blue lights everywhere else (front, fog, side mirror turn signal)
What do you think?
