How dark should I tint them for

A. Safety
B. Looks

I want it to be noticeable when I'm hitting the breaks, and stay away from getting pulled over

But I want them to look nice and dark for my dark blue a6

Thanks

 

hella smoke should look good~ but more expensive...not sure what % though...sorry...

 

20-30%...keep it on safe side

 

 

i wouldnt go any lower than 35%. any thing lower than that and your askin to get a ticket

 

What do these tail light percentages look like with brake lights on and off?

kinda wanting a visual.

What about that a6, what percentage is that?
