Abstract: A mounting bracket for a bicycle light is disclosed which is formed in two parts, a first part for mounting on part of a bicycle frame, the first part having a first magnet, and a second part having an elongate portion arranged to extend laterally away from the plane of the bicycle frame. The elongate portion is arranged for holding a light source at a distal end, and having a having a second magnet arranged towards its proximal end. The second magnet configured to engage with the first magnet to couple the first and second parts together. The first and second parts are further provided with cooperating engagement portions for selectively elastically engaging the first and second parts with one another. Optionally the first and second parts have cooperating alignment portions to help ensure that the coupling occurs at a desired orientation.
