How do I lock out my flashlight tailcap switch?
First make sure your flashlight is functioning. Then unscrew the tailcap until the light will not turn on when you press the tailcap switch, or when you wiggle the tailcap from side to side. If the flashlight does not turn on, the tailcap switch is locked out. You may wish to unscrew the tailcap another ¾ turn to be absolutely certain it’s locked out. If your tailcap has a small “scoop” mark in the rim, use this for future reference to determine how much the tailcap should be unscrewed to lock out the switch. NOTE: After locking out your flashlight, always push the tailcap switch to make sure it is truly locked out.
