In looking at it further, I found the "catch". If one opts for the "high and low beam" option, the bulb has to have a solenoid to actually move the bulb in and out to change the angle of light against a reflector. Most HIDs are like this. So, in the case of our era of bikes, all the wiring junctions will have to be moved elsewhere, and a hole might have to be made in the rear of the bucket. Not a deal breaker, but be aware of the work involved.
My daughter has a Nissan Rogue that has these headlights. It actually has a servo instead of a solenoid. You can fine tune it from the drivers seat up and down.
