My trusty titanium mini CR2 that I've been carrying for years stopped working all of a sudden. It's still in the 10 year warranty but when I checked the website, it looks like the CR2 mini isn't made anymore. I'm hoping they/you have spare parts still, but if not, what are the options? Can any of the new mini parts fit inside my CR2 sized titanium head? This has been my most carried light for years, and probably the best, most convenient and robust all around useful light I've ever owned. I don't want to give it up.
