I like this small Sigma aura 30 bike light (powered by AA batteries), and it seems I'm not the only one; the provided mount is not allowing to secure the light on the bike and I got one stolen.
This mount is reasonably strong and allows to choose freely the inclination of the light.
To fit the light on the mount you have to reuse the spring and screw provided with the original mount.
