What is a red light readable map?

A red light readable map is a type of map designed for use in low-light or nighttime conditions, featuring red-colored text and graphics. The red color helps preserve night vision while still providing essential navigational information. These maps are often used by military personnel, outdoor enthusiasts, and in emergency situations where maintaining visibility is crucial without compromising night adaptation. The design minimizes glare and distraction, allowing users to read the map more effectively in darkness.
