Wings of Justice (a.k.a. Angelic Wings or Eternal Light) are a PC-exclusive vanity item for Diablo III. They are only available to players who have purchased a Collector's Edition of Diablo III.
When used, they apply or remove "a display of heavenly power": glowing angelic wings, blue like those worn by Tyrael.
When obtained, they can be added to Wardrobe. Only one set of Wings can be equipped at a time. If equipped, they will be visible even in character selection screen.
They shine with the power of the eternal conflict.
