Merge suggested (merge with cateye then delete, use images as required in other consumable that give the exact same effect, otherwise take new images if their effect differs in color, tone and level etc.)
Low-Light Vision is an ability in Fallout: New Vegas. It is granted by a few consumables, such as cateye, Nuka-Cola Quartz, Ghost sight with the Dead Money Add-on, and the Friend of the Night perk. The effect is almost identical to Night-Eye in Bethesda Softworks' Elder Scrolls IV: Oblivion. The two pictures below demonstrate the effect.
