The most apparent use of a flashlight in an emergency kit is lighting your environment, indoor or outdoor. Emergencies don't occur exclusively at night, but many factors like terrain and easily navigable obstacles during the day become extremely dangerous at night if you can't see them. Making sure to have a high-quality flashlight will mitigate this danger significantly. To lighting the way at night, flashlights can be used to find people who require rescue, and a great tool for people who need rescuing to signal for help. If you are stranded at night without a flashlight, it is nearly impossible for rescuers to see you.
