If we have a description of this manufacturer's warranty, it will be listed below; however, we advise that you contact the manufacturer directly for specific details.
All Streamlight flashlights, lanterns and head lights carry a no-quibble warranty that's honored at Authorized Service Centers around the world. We call it 'bulletproof' because it covers vital parts of the light: from the switch and the lens to the case and the reflector.
