Signal

The signal icon represents a mobile or cellular signal, symbolizing connectivity and communication. It originates from the concept of signal strength in telecommunications. The icon is widely recognized as an indicator of network signal quality.

In software and platforms, the signal icon appears in various contexts, such as mobile device status bars, network settings, and communication apps. For example, it is commonly seen in mobile operating systems like Android and iOS, indicating the strength of the cellular signal.

From a UX perspective, the signal icon communicates the availability and quality of network connectivity to users. It helps users understand whether they have a stable connection, allowing them to access online services, make calls, or send messages.

Signal is one of 304 icons in Material Design Light, made by Pictogrammers and released under Open Font License. It is drawn on a 24 × 24 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 SignalIcon to components/icons/mdi-light-signal.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 SignalIcon 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 Signal icon, or any of 304 Material Design Light 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.

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="Signal", so screen readers say what it does.

Yes. SignalIcon passes every SVG prop to the svg element, so <SignalIcon 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. The Open Font License allows commercial use; the icons can't be sold on their own. The full terms are in the license, linked on this page.

No visible credit is required: Open Font License 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 Material Design Light, Pictogrammers and the license.

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