About the Lightbulb black outline 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 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.
