About the Idea Lightbulb black outline icon
A rounded bulb glass sits above a ribbed screw base, and eight short rays fan out from the glass on all sides to show it lit. It carries the classic meaning of a new idea, insight, innovation and creative energy. Place it on brainstorming boards, startup and agency websites, e-learning modules, pitch decks, tip callouts and product feature lists that highlight smart thinking.
The rays are spaced evenly and kept clear of the glass so the silhouette stays open, while the two banded rings at the neck give the base its bulb identity. It pairs with brain, rocket and target icons. If the rays crowd at 16 px, crop to the bulb alone.
This is the black outline version of the idea 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.
