The Kanohi Ruru is the Mask of Night Vision. The Great version allows its user to cast a beam of light that allows them and those nearby to see. It also grants them normal night vision and a small degree of x-ray vision. It can be used as a weapon, blinding enemies with its glow. The Noble version does not glow, but allows its user to see clearly in any level of darkness.

Kanohi Ruru are made from Enlarge and Teleport Kanoka on Metru Nui.[1]
