I'm sure you recall the fellow FJR pilot and Iron Butt veteran Rick Martin made this identical conversion to his PIAA 910 lamps. I have seen his in action.... they are pretty stunning.
Getting the thread back on track.
I did not know this. I suspected it would work well, since the 910 reflector and lens is such an excellent design to begin with. I got to run my 910's once at the OEM 110 watts each before having to step them down to 85 watts each so they wouldn't kill the Gold Wing. In spite of the decreased output, they still did journeyman duty at NV Outback speeds many times.
With the FJR I had to step them down to 55 watts each and they are okay but just a shadow of their former selves. I suspected that an HID conversion would compliment their hidden potential exceptionally well. To hear that they have been tested and endurance-rider-approved in just that way is a welcome confirmation!
