You have to decide how you want to wire them. I bought the Kensun HIDs from Amazon and wired it so that the low beam turns on halos and the hi beam turns on both. Or you can do it the way it comes from the factory where the low beam turns on only the lo beam light and the hi beam turns on only the hi beam light.
I've got a set as well. One thing I might add, if you have the pre- Customer Satisfaction Headlight Housings...do those as well as they will continue to deteriorate.
I bought DDM's for my firebolt a few years back and they work great!, however I just ordered a set for my triumph and the finish of the kit just seems a bit lower than what it was a few years ago.
