Its the adjuster mounts that will have gone. Mine went ages ago.

You can rebuild them to a fashion, but it doesn't last longer than 6 months.

The problem is, you cannot get in to rebuild the mount. If you take the lens off you still cannot get to the mounts, you have to do it from the back of the unit.

After a couple of times, repairing it gets a bit boring, and paying for a new light starts to look attractive !
