About the Idea black outline icon
A filled round light bulb glows with eight straight rays fanning out on all sides, sitting on a short collar above a ridged screw base with a small contact tip. The bulb-plus-rays pairing is the shortest way to say a thought has just landed. Use it for tip and hint callouts, innovation and R&D pages, brainstorming and note apps, feature announcements and creative agency slides.
Because the bulb is a solid mass and the rays are thin strokes, contrast does the work and the icon stays punchy even as a tiny inline marker next to text. It pairs with brain, target and rocket icons in a strategy set. Leave clear padding around it so the rays do not collide with neighboring elements.
This is the black outline version of the idea 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.
