The Interstate model, according to the manual, has separate left and right indicators for the signals. The other two do not, and need the diodes. You'll need to refer to the wiring for your other bike, if you wish to change it, too.
Thanks, I don't think I'm going to do the LED turn signal conversion on the Goldwing. I did install the LED Tail/Brake lights. I really don't ride the Goldwing that much anymore but I've had it so long I really don't want to get rid of it. It only has 36K miles on it and it's a great bike, I ride the Valkyrie most of the time.
