Does anyone have Smoke or Clear taillight lenses on their Mustang? Most online stores advertise these tail lights. But next to these products it says "For off-road use only" What does this mean? They're not good for using on normal street driving? Or are cops just are picky about tail light lenses? Why would stores advertise these lenses for "off-road use only"? Any information would be helpful since I am looking into buying the smoke type.... they look sweeeet.
