Outline icon of a lightbulb with radiating rays and a ringed screw base symbolizing an idea
About the Lightbulb black filled icon
The icon shows a rounded lightbulb with short radiating dash lines around the top signaling light or a spark of insight, a curved glass highlight inside, and a ringed screw-thread base. It represents ideas, innovation, and inspiration, fitting brainstorming tools, tips and FAQ sections, energy apps, and startup or product landing pages.
The symmetric bulb has evenly spaced rays around the crown, three horizontal rings mark the screw base, and a single curved line adds a glass-highlight detail. It pairs with gear, brain, and rocket icons for innovation themes, and reads clearly even at 16px.
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.
