How do you flash SOS with a flashlight?

Three quick, three slow, three quick.

  1. One long flash every minute
  2. Two quick, two slow, two quick
  3. Three quick, three slow, three quick ✔

Why: SOS in light is three short flashes, three long, three short. Use it wisely, because flashing drains your batteries.

Huh, didn't know that: Illumination, a flashlight or headlamp with extra batteries, is one of the NPS 10 Essentials.

The dad joke
Why did the flashlight go to school? It wanted to be brighter.
