As armed citizens or professionals, we seek to be properly prepared for the challenges we face. We purchase the right gear, train, and keep a proper mindset to protect ourselves and those we love. We continually assess our readiness, and if presented information on needed improvements, we will thoughtfully consider implementing new training, gear, or procedures to support.
We are particularly interested in the role of lighting conditions during violent encounters. The question is how often would a weapon mounted light be effective? How often do violent encounters happen in darkness?
One reputable source of data is the annual FBI Law Enforcement Officers Killed & Assaulted statistics. As of this writing, the most current year included is 2019. Of particular interest is the section on lighting conditions. This data indicates that 27% of incidents occur in the dark. It is unknown what additional percentage occurred in low-light situations.
In addition, we can see that most incidents occur outdoors. Incidents that occur both in the dark and outdoors typically have longer distances involved, and a less controlled environment, where additional lighting can be effective in providing information necessary for defense.
This data helps drive home the need to carry a flashlight to help identify and control threats in low light. While a handheld light is an important tool, a weapon mounted light provides more effective lighting if you need to deploy your handgun.
