About the Light Bulb black outline icon
A rounded bulb with a ribbed screw base sits inside eight short rays that suggest it is switched on and giving off light. The shape is shorthand for ideas, inspiration, insight and electricity. Drop it into tip callouts and onboarding hints, brainstorming and note-taking apps, startup pitch decks, energy-saving pages, and blog article headers.
The glass envelope is drawn as a single wide arc narrowing into the neck, and the base is marked by three parallel lines with a small contact at the bottom. Rays are evenly spaced around it. Pair it with gear, rocket and target icons; keep the rays visible by using 24 px or larger.
This is the black outline version of the light bulb icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
It downloads free as an SVG vector or transparent PNG in seven sizes, and the free online editor lets you recolor it, apply gold, silver, neon and gradient styles, add animation, or convert it to EPS, PDF and DXF.
