These were supposed to come with the correct adapters for my bike but they did not. I did have to cut the connectors from the original turn signals and solder them to the new signals. That left the original signals without connectors and basically useless without some effort.
I will say that once the signals were modified they now work beautifully and look great on the bike. I especially like the sequential led operation.
I would not have purchased these knowing that I had to cut and solder and I would not recommend them to anyone who doesn't want to splice wires.
