MEASURES 66.5MM / 2 5/16" CENTER TO CENTER OF SCREW HOLES THE LENS'S ON THESE HAVE A MARK ON THE TOP WHERE THE WIRE WAS STRAPPED TO IT WITH A RUBBER BAND FOR THE LAST 30 TO 40 YEARS. SOME HOW THE CHEMICAL REACTION BETWEEN THE WIRE'S INSOLATION AND THE PLASTIC MAKEUP OF THE LENS MADE THE WIRE MELT INTO THE LENS, SO IT LOOKS LIKE A HOT WIRE TOUCHED THE TOP OF THE LENS. SORRY THEY ARE ALL I HAVE. THIS CAN TAKE A 12V BULB ALSO THESE SAY MADE IN JAPAN ON THEM TAIL LAMP ASSEMBLE THIS FITS LOTS OF PRE "68" HONDA'S BUT FOR SURE THE CT200'S.
