Has anyone ever used these before on their cars?

Wondering if they block any of the light at all, of they still shine through with no problems. Can anyone clarify?

Oh and I prefer to do this versus spray tint because at least with this if I get bored with it, I can just rip it off in 2 seconds.

 

i have the black out on my tails. if you know how to apply vinyl they are much better than spray in my opinion since they are easier to get off if you ever need to. and they let about 70% of light out and block 30% they aren't too dark and get the job done. if you want i can take a few pictures of them on the accent tails.
