About the Brain Idea Light Bulb black outline 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 black outline version of the brain idea light bulb icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
It downloads free as an SVG vector or transparent PNG in seven sizes, and the free online editor lets you recolor it, apply gold, silver, neon and gradient styles, add animation, or convert it to EPS, PDF and DXF.
