Just got some of these in for T&E. All I can say is WOW! These tailcaps turn your ordinary flashlight into a strobe! They also give you a constant on capability without having to twist the tailcap. The tailcap also features a lock out capability. Last, but no least, the tailcap can also tell you if your batteries are about to go!
Here is how it works. A quick press and release gives you constant on. Quick press and release turns it off. A continuous press gives you seven strobes a second!
The tailcap is compatible with most every SF light made (G2/9P/6P/Millenium series/Z2/G2Z). They are also working on some for the Executive series as well.
Colors available are Natural HA and Black HA
