What is the disadvantage of securing the Sidewinder flashlight in the IR mode?

Securing the Sidewinder flashlight in the infrared (IR) mode can lead to issues with visibility and signaling effectiveness. When used in IR mode, the flashlight emits light that is invisible to the naked eye but can be seen by night vision devices. This characteristic makes it highly suitable for covert operations. However, if the intention is to communicate or signal to someone who does not have night vision capabilities, the IR mode would be ineffective. Consequently, the flashlight may not effectively alert or guide individuals without the appropriate gear, thereby creating challenges in communication and coordination.

This practical consideration illustrates that, while the IR mode is beneficial in certain tactical scenarios, it can indeed limit the versatility of the flashlight when signaling is required.
