About the Brain Idea Light Bulb black filled icon
A light bulb holds a two-lobed brain inside its glass, with short rays radiating outward and three horizontal lines forming the screw base. The bulb signals an idea while the brain puts thinking and knowledge behind it. Use it for innovation sections, brainstorming tools, e-learning platforms, psychology blogs, startup pitch decks and research presentations.
The brain fills the bulb almost edge to edge, and the evenly spaced rays keep the mark circular within its ring. It works beside gear, rocket and target icons in strategy sets. Drop the outer ring below 24 px so the brain folds remain readable.
This is the solid black filled version of the brain idea light bulb icon: a bold silhouette that reads clearly at 16-24 px and on dark or busy backgrounds, and prints well in one colour.
