At one time I considered changing all my lenses to smoked.
After my buddy changed the taillight on his SG to smoked
I changed my mind as you can barely see it night or day.
I'll stay with red rear & amber front,and be more visible.

 

I did change my T/S lenses to smoked with amber lamps, still very visible when in use and the fronts have parking lamp elements so they are on all the time as amber just no color when shut down.

I am also looking into a SG front fender or maybe some other style to clean up the lines some, I still like my RK as a King but it seems a bit gawdy at times up front.
