If you carry the Poly Stinger or the Stinger LED, 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 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.
