Light bulb with a ridged screw base and eight short rays of light around it
About the Bulb black outline icon
A rounded glass bulb sits above a ridged screw base with a small contact tip, surrounded by eight short rays spaced evenly around the top and sides to show it is lit. The mark stands for ideas, hints and new thinking, which fits tip callouts in apps, brainstorming and innovation slides, energy-saving pages, startup websites and help documentation.
The glass is drawn as a wide teardrop with a narrow neck, and the two ring lines at the base add the screw-thread detail that separates it from a plain bulb shape. It sits well beside gear, rocket and target icons. The rays read best at 32 px and up; trim them for tiny toolbar use.
This is the black outline version of the bulb icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
