The Camillus Thrust #19275 flashlight may initially not turn on. The flashlight has a battery pack that has plastic packaging on it to ensure that the flashlight does not turn on prior to use. This may affect the flashlight from fully operating. Once the plastic packing is removed from the battery pack the flashlight should operate properly.
To access the flashlight battery pack:
1. Unscrew the top piece of the tactical pen, which will reveal the batteries
2. Flip the pen so that the batteries dump out.
3. Remove the plastic packaging around the batteries.
4.Place the batteries back in the pen facing up. If the batteries are not facing up the flashlight will not work.
