Spark Lens

Spark Lens (スパーク レンス Supaku Rensu) is Daigo Madoka's transformation item. He uses the item to transform into Ultraman Tiga. Daigo gets the Spark Lens immediately after merging with the Tiga statue, as it appeared in his jacket after he transformed back. It is appearantly his by defealt as the reicarnation of Tiga he was destined to receive it. Unlike the Beta capsule which requires the push of a button, the Spark Lens is activated by pressure on the grip, at times Daigo has transformed without it, appearantly under emotional stress or during a great fall. At the end of the series the spark lens disintegrates.

Dark Spark Lens
Dark Spark Lens  (暗い火花レンズ Daaku Supaku Rensu) is Daigo Madoka's other transformation item. Dark Spark Lens is a dark version of Spark Lens. Which allow Daigo to transfrom into Tiga Dark. As Tiga Dark is implied to be the original form of TIga, the Dark Spark Lens is implied to be a copy of the Spark Lens original form. What became of it is unknown as Daigo is never seen transforming again.
