About the Lightbulb black filled 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 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.
