That's an awefully thin tube back there, and it's angled different from the seat post.
The LD1000 will attach to any US-type two-hole reflector bracket. It comes with a coarse-thread screw for that purpose. If the bracket is not very thick, put a washer under the head of the screw so it doesn't go into the light too deep (causing a bulge in the wall of the battery compartment).
Besides the screw, they also come with a belt clip (not a good idea for an LD1000 because aim is critical) and a seatpost-mounting bracket.
LD1000's are a rear-heavy light, and may bend or break light-duty reflector brackets over the course of time. They are also very directional, so they must be mounted rigidly and aimed just right if you want them to be effective. Here's a bracket I rigged for an LD1000 that I was giving away:
This bracket is made of parts from two nylon reflector brackets, and it allows the light to be angled just right. If you're a good customer of a local bike shop, ask them to do you a favor and help cook up a good strong mount for your LD1000.
