There are reflector brackets made to go onto the back of any rack.
It will also screw directly to a rear facing hole in a rack. And you can buy clamps of just about any diameter from the Cateye website. It will mount on almost anything, just like a reflector.
I don't have my LD-1000 in front of me, but from memory, there are holes molded into the back of the light that line up with the reflector bracket holes (at least on my Delta rack) but they are not threaded and very shallow. How do you go about using these? Maybe sheet metal screws? Can you drill/screw into the body of the light without puncturing anything important or cracking the plastic?
