About the Lightbulb black filled icon
A pear-shaped glass bulb narrows into a ribbed screw cap and rounded contact tip, with short straight rays spaced around it to show that it is switched on. The glowing bulb is shorthand for ideas, insight, invention and saving energy, so it fits tips and hints panels, product feature lists, brainstorming tools, startup decks and utility or smart-home dashboards.
Rays are detached from the glass, which leaves breathing room and keeps the bulb silhouette clean, and the base bands add just enough detail without crowding. Pair it with gear, rocket and target icons in an innovation set, and drop the rays if you need a version that sits tightly inside a button.
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.
It downloads free as an SVG vector or transparent PNG in seven sizes, and the free online editor lets you recolor it, apply gold, silver, neon and gradient styles, add animation, or convert it to EPS, PDF and DXF.
