Lightning Fill

The lightning-fill icon represents a lightning bolt with a fill, often used to symbolize electricity, energy, or power. The visual design of this icon is a stylized representation of a lightning bolt with a filled shape, conveying a sense of dynamic energy. This symbol originates from the depiction of lightning in various forms of art and design.

In real-world applications, the lightning-fill icon appears in software and platforms related to energy, weather, and electronics, such as power management tools, weather forecasting apps, and electrical engineering software.

From a UX perspective, this icon communicates a sense of energy, power, or sudden change, helping users understand functionality or navigate interfaces related to energy management or electrical systems.

Lightning Fill is one of 2,084 icons in Bootstrap Icons, made by The Bootstrap Authors and released under MIT. It is drawn on a 16 × 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 LightningFillIcon to components/icons/bi-lightning-fill.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 LightningFillIcon 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 Lightning Fill icon, or any of 2,084 Bootstrap Icons 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 16 × 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="Lightning Fill", so screen readers say what it does.

Yes. LightningFillIcon passes every SVG prop to the svg element, so <LightningFillIcon 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. MIT 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: MIT 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 Bootstrap Icons, The Bootstrap Authors and the license.

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