13. Miniature Flashlight
A lighter can enable you to see the area near you for short periods of time, but a miniature flashlight is much more practical in the dark. Make sure that you invest in a quality product such as the Streamlight 73001 so that you are able to take advantage of a long battery life and bright LED light. This particular flashlight can also be clipped on to your jacket or key-ring so that you can keep it handy at all times. Another bonus of having a good flashlight is that it can help you capture the attention of a rescue team after a plane crash.
