Does the bracket hold the light on a bumpy track? I would like to mount the rear light on my gravel bike. I often ride on gravel tracks, which can generate strong vibrations. As I can see from the pictures, it's just a plug-in connection between the light and the bracket. Will it hold? Has anyone used it like this and can say that the light is still firmly attached even after being taken off x times and riding x kilometres of gravel road? Merci
