ok i know not everyone approves of this but im seeing to many civics with si tails...so with vht nightshades can you determine the darkness and i know this is a stupid question but does it go on the inside or outside...i only want a light tint not black thats why i ask

 

the darkness of the lights all depends on how many coats u put on them. and u just spray it rite on the outside of the lights. if u only want a very light coat u should do 2 coats. 1 coat u cant really tell that u did anything to them. and 2 coats u can just see it
