About the Thinking Head Lightbulb black outline icon
A side-facing human head drawn as a single open contour, with a lightbulb and short radiating rays placed where the brain would be. The pairing reads instantly as thinking, having an idea, problem solving and creative insight. Use it on brainstorming tools, innovation landing pages, e-learning modules, product strategy decks and onboarding screens that explain how a feature works.
The head outline is left open at the neck so the figure sits on the baseline, and the bulb's screw base and filament arc are simplified into two stacked bars. It pairs naturally with brain, puzzle piece and target icons in the library. Keep it at 32px or larger so the bulb rays stay readable.
This is the black outline version of the thinking head lightbulb 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.
