Lightbulb

The lightbulb icon represents a light bulb, often used to convey ideas or inspiration. It originates from the Firefox OS Emoji library, designed by Mozilla. This icon is commonly used in digital interfaces to represent an idea or to add a touch of creativity.

In software and platforms, this icon appears in various applications where ideas or inspiration is essential, such as in brainstorming tools, educational resources, or creative software. For example, it might be used to indicate a new idea or to add a creative touch to a user interface.

From a UX perspective, this icon communicates a sense of creativity or inspiration, helping users understand the tone or personality of an interface. It can be used to draw attention to a specific feature or action, making it more engaging.

Lightbulb is one of 1,034 icons in Firefox OS Emoji, made by Mozilla and released under Apache 2.0. It is drawn on a 512 × 512 grid.

Sign in (it's free), then open Get icon, Install with shadcn CLI, and pick your package manager to copy the command. It adds LightbulbIcon to components/icons/fxemoji-lightbulb.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 LightbulbIcon 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 Lightbulb icon, or any of 1,034 Firefox OS Emoji icons, and install it from a prompt.

It's multicolor, so it keeps its own colors.

Set width and height on the component, or a class like size-6. It's drawn on a 512 × 512 grid, so it stays sharp at any size. Customize also sets the size it exports at, its padding and rotation.

Yes. It keeps its own colors in light and dark mode, so check it against both backgrounds. 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="Lightbulb", so screen readers say what it does.

Yes. LightbulbIcon passes every SVG prop to the svg element, so <LightbulbIcon 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. Apache 2.0 allows commercial use; keep the license notice when you ship the icons' source files. The full terms are in the license, linked on this page.

No visible credit is required: Apache 2.0 only asks that you keep the license notice if you ship the icons' source files. Icons installed with the shadcn CLI already start with a comment naming Firefox OS Emoji, Mozilla and the license.

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