I currently have the civic fogs, I'm thinking about smoking them out. The thing that I'm wondering is that if i get 3k or maybe 12k will it show through the smoked fogs really well or would it be a little dimmed?
If you want to see anything using your fogs, don't use 12k. Put some 3k-5k in there and they will make sufficient light. The film should not hinder the output.
