Available individually or in packs of three so every scope in your case is always ready to go - no more constantly swapping your light source on/off different scopes every time you need a different view.
 
STINGER Micro LED Light Sources are designed to make it quick and easy to switch scopes at any point during a safe job by eliminating the need to stop and change over light sources. Just keep STINGERS attached to all the "go to" scopes in your scope case and they'll always be ready to go. STINGERS are brighter than a standard Mini-Mag but a fraction of the size. Rotate the STINGER head for constant on or push the end for momentary on.
