Signal 3

The signal-3 icon represents a signal or signal strength indicator with three bars. It is commonly used to indicate the quality of a network or connection. The icon is often used in various digital products to provide a clear and recognizable way to display signal strength.

In software and web applications, the signal-3 icon is frequently used in network management systems, mobile apps, and communication platforms. It is often accompanied by other icons or text that indicate the signal strength or connection quality.

From a UX perspective, the signal-3 icon communicates the idea of signal strength or connection quality. It helps users understand the reliability of their connection and provides a clear and easy way to assess the quality of their network.

Signal 3 is one of 799 icons in SmartIcons Glyph, made by SmartIcons and released under CC BY SA 4.0. It is drawn on a 17 × 16 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 Signal3Icon to components/icons/si-glyph-signal-3.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 Signal3Icon 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 3 icon, or any of 799 SmartIcons Glyph 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 17 × 16 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 3", so screen readers say what it does.

Yes. Signal3Icon passes every SVG prop to the svg element, so <Signal3Icon 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.
