The light is an automatic water activated light type with a manual on/off switch, and a constant light type. It is activated by moving the activation arm around the comer clockwise thereby enabling the automatic mode. The light will then tum on, if in contact with water. After being activated, the light stays turned on disregarding the water contacts are lifted out of the water. The light is deactivated by moving the activation arm around the comer anti clockwise. If the light after disruption is brought back to automatic mode, and water contacts are dry, splash water on the contacts and the light goes on again. Activation and deactivation is clearly marked on the label.
