Dylan, it's a Cateye LD1100 with a Cateye rear carrier mounting bracket to adapt to the German standard 50mm spaced horizontal eyelets on the rack. I thought for a while about using the Busch and Moller tail light which is practically designed to fit Tubus racks, but decided it was too ugly and crap. The Cateye is actually installed upside down so that it can be removedby quick release. I hope it doesn't fall out.
