The streamlights are all a P.O.S.
Survivor light lasted 1.5 years and took a crap, So I bought the Fire Vulcan and that battery
died 1 year and 2 months to the day... I just replaced the battery, (Not Cheap)
A few fellow brothers have had problems with both the battery and the light bulbs falling out inside the housing...
For the money these things cost you would expect a better quality light...
You would be better off buying a small LED flashlight from the parts store for 3-4 bucks and they come with batteries
