Hiya,
All Petzl products come with a three year warranty. ( Though you'll probably need your receipt). Though Lyon Equipment the UK importer are usually pretty good on warranties. One thing I'll say about French wiring ( not jingoistic just something I've noticed in their torches and cars over the years) is that after 12 years it just goes "on the fritz". Usually a good clean of all the contacts is enough in the torches, though on certain models the wiring loom was a little more friable due to the way it is routed.
Where are you based as I'd be happy to have a look? I'm in Perthshire.
Cheers
Goatboy.
