The Kanohi Ruru was the Mask of Night Vision. The Great Ruru gave its user the power to see clearly in darkness and a limited amount of x-ray vision. It also allowed them to cast a beam of light for illumination, which could be used to blind opponents. The Noble Ruru only allowed its user to see clearly in darkness.
- Great: In BIONICLE 2: Legends of Metru Nui, Toa Metru Whenua used his Ruru to illuminate a cave that Turaga Lhikan, Onewa, Nuju, and himself walked through. He later used his Ruru to see through the floor of the Coliseum.
- Noble: In BIONICLE Chronicles 4: Tales of the Masks, Turaga Whenua used his Noble Ruru to watch two Manas fight each other.
