Bulb

The bulb icon represents an idea or inspiration. It is often depicted as a lightbulb with a glowing filament. The lightbulb symbol has been used for over a century to represent innovative thinking and is commonly associated with Thomas Edison's invention of the first practical incandescent lightbulb. The icon's visual design typically features a rounded glass bulb with a metal base and a glowing filament inside, symbolizing the spark of creativity and innovation.

The bulb icon is commonly used in software and platforms related to creativity, innovation, and problem-solving. For example, it appears in tools like MindMeister, a mind mapping software, and Popplet, a digital bulletin board app. It is also used in educational platforms like Khan Academy and Coursera to represent learning and knowledge.

From a UX perspective, the bulb icon communicates the idea of insight or understanding. It helps users navigate interfaces by indicating where they can find creative tools or solutions. For instance, in a digital design platform like Canva, the bulb icon might be used to suggest design ideas or inspiration.

Bulb is one of 715 icons in coolicons, made by Kryston Schwarze and released under CC BY 4.0. It is drawn on a 24 × 24 grid with a 2 stroke.

Sign in (it's free), then open Get icon, Install with shadcn CLI, and pick your package manager to copy the command. It adds BulbIcon to components/icons/ci-bulb.tsx: one file, a size prop (24 by default) and every SVG prop, with no icon package.

Copy it as React (from Get icon, or the Code section): a typed BulbIcon component you paste into your project, with no package to install. Only the icons you import reach your bundle. It works in Next.js and any React app.

Open Get icon, then Copy as code, and pick Vue, Svelte, Angular, Solid or Preact; the Code section shows each one too. Every version is one self-contained component with the SVG inside, and SVG and data URL copies are there for plain HTML and CSS.

With Pro, the shadcn.io MCP server lets Claude Code, Cursor or any MCP client find the Bulb icon, or any of 715 coolicons icons, and install it from a prompt.

It's drawn in currentColor, so it takes the text color wherever you use it: a class like text-primary recolors it. To bake a color in, set one in Customize before you copy.

Set width and height on the component, or a class like size-6. It's drawn on a 24 × 24 grid, so it stays sharp at any size. Customize also sets the size it exports at, its padding and rotation, and its stroke.

Bulb is a line icon drawn with a stroke width of 2. Change it in Customize before you copy, or pass strokeWidth to the installed component when all of its strokes share one width.

Yes. It follows the text color, so with text-foreground (or any theme token) it changes with your light and dark themes. The icon is a vector, so it needs no separate dark asset.

Next to a visible label it's decoration: add aria-hidden="true" so screen readers skip it. Standing alone, as in an icon button, give the button a name instead, like aria-label="Bulb", so screen readers say what it does.

Yes. BulbIcon passes every SVG prop to the svg element, so <BulbIcon aria-hidden="true" /> works, and so do role="img" with aria-label, or a title child, when it carries meaning on its own.

Yes. Open Get icon, then Download file: SVG for code or design tools like Figma; PNG, WebP or JPEG at 512px; or an ICO favicon with 16, 32 and 48px inside. Each one uses what you set in Customize.

Yes, with credit: CC BY 4.0 asks you to credit the author (Kryston Schwarze) where you use the icons. The full terms are in the license, linked on this page.

Yes. CC BY 4.0 asks you to credit the author where you use the icons, for example "Icons by Kryston Schwarze, CC BY 4.0" on an about or credits page.

Yes. Copying and downloading it is free, and the shadcn CLI install only needs a free account.
