About the Lightbulb black filled icon
A rounded light bulb with a ribbed screw base sends out eight short rays in every direction, showing the bulb switched on. It stands for ideas, insight and innovation as much as for lighting itself. Use it for tips and hint panels, onboarding walkthroughs, brainstorming tools, energy saving pages and pitch-deck slides about new concepts.
Even ray spacing around the glass creates a sense of glow without shading, and the segmented base keeps the bulb recognizable at small sizes. It pairs with gear, rocket and question mark icons. Remove the rays to build a matching off-state variant for the same set.
This is the solid black filled version of the lightbulb icon: a bold silhouette that reads clearly at 16-24 px and on dark or busy backgrounds, and prints well in one colour.
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.
