Hey, thanks for replying, folks! Here are my short comments on what you told me -
I've got projector lights, so that reflector gives pretty much nothing to me. It is the lens that matters and projects the ray.
OMG, I even haven't thought of that! I've always thought that they do not allow tinting headlights red, because someone can confuse the vehicle with cops or something, you know. You are absolutely right, and thanks for commenting on that.
Thanks, will check it out tonight, let's see how people do it. If it's way too complicated maybe I'll just give up this idea haha
