these should not be mistaken for "black out" lenses that affect light on situations. In fact, because they have no light coming back in from the backside when the lights are not on, they are very light tint ,i would say about 80% if compared to tint film. But when the lights are off, they just elim the red, when the LED for brakes or anything lights up , it's virtually the same as no lens at all. We mounted one on and the other stiok, almost imperceptible. I take my mods very carefully, I don't do boy racer mods and researched this with the owners of gscreations (they are local) as I said in my original post. I personally think its safe.
but to each his own, not trying to convince anyone to do it, we all are different...
but boy racer black outs are dangerous for all concerned - I often quote an LEO forum:
