Non-issue.
The stock mount that comes on the Luxos-U and many other B&M lights works just fine with road caliper brakes and standard fender mounts. That’s the mount I use on my blue bike with Shimano BR-651 mid-reach road calipers and SKS P-35 fender.
Worst-case scenario is that you'd have to get a longer nut for the back side of the fork crown. Stock item at the LBS. They may even just give you one.
It's a little tricky getting everything tightened down and straight. Four hands would help. But once it's done, it's done.
Pic of the mount. It's just bent wire. Stainless too.
I use that B&M mount with my Schmidt Edelux on the blue bike.
