The Reusable Mini Emergency Light is a convenient LED emergency light powered by a small, replaceable water activated fuel cell. Two bright LEDs provide directional light to illuminate areas or situations where bright light is needed away from access to conventional batteries or electrical grids. The Reusable Mini Emergency Light can be stored prior to first use for years in its hermetically sealed packaging. It is activated instantly to full capacity simply by dipping it in water. Once activated it will operate continuously for several days with a few additional dips in water. Replacing the fuel cell with a new one will restore it to a like-new condition.
