Outline light bulb with short rays radiating around it and a screw base
About the Lightbulb black outline icon
A classic pear-shaped light bulb glows with eight short rays spaced around it, sitting on a ribbed neck and a stepped screw base. It is the standard shorthand for ideas, insight and innovation, and it also works literally as lighting. Use it for tips and hints, feature highlights, brainstorming sections, onboarding callouts and energy or electrical service pages.
The rays are spread evenly on all sides, so the bulb stays centered in a square grid, and the wide base gives the shape weight. Pair it with brain, rocket, gear and target icons. At 16 px drop the rays or switch to a plain bulb version.
This is the black outline version of the lightbulb 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.
