Ray, sounds like the switch has a problem. Streamlight is usually really good about fixing things. If you can drop by a Stream retailer in your area, they will probably give you a new tail cap. Or contact STREAM directly.
One thing, when you screw the tailcap tight, does the light come on? I have a SUREFIRE that does that, but I dont have a twist on Streamlight.
