The light was 249.95 a little over 5 years old. I have mine mounted on my Tubus rack. It sets above my busch&muller taillight. The light set comes with an extension and several brackets for different diameter tubes. I used a tubus fender bracket upside down and a nitto light mount. Nitto makes Two light mounts. One with a 5mm mounting bolt and one wath a 6mm mounting bolt. The tubus fender support has a 5mm hole.
