If you carry the Stinger, Ultra Stinger, or the Stinger HP, you know
the size of these flashlights vary depending on the model. There is no
way you can break a window with these flashlights without causing
damage to your expensive light or injuring someone from flying glass.
Attaching Bust A Cap® to your flashlight will insure that it will break
glass with just one tap and not damage your equipment.
Warning:
Please remove the o-rings from the old cap and put on your new Bust a
cap to insure that your light remains water tight.
