About the Lightbulb black outline icon
A rounded incandescent bulb glows with eight straight rays fanning out on all sides, above a ribbed screw base that narrows to a small contact tip.
The lit rays turn it into a shorthand for a bright idea, insight, innovation or a helpful hint. Use it for tip callouts and onboarding tooltips, brainstorming and strategy slides, energy-saving dashboards, learning platforms and blog article headers.
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.
