Hi Wello, the combined stop/turn/tail light units are sealed LED units, so you can't change the lenses to the smoked ones unfortunately. I had the same issue on my Iron and endeavour up changing the fronts over to the smoked lenses and orange bulbs, but left the rear ones unchanged. I have seen some guys tint the rears with tinted clear coat paint but it I have never tried it myself. Hope that helps you. TC
