Bulb black filled icon
Outline light bulb with a rounded glass top, two base bands and a small contact tip
About the Bulb black filled icon
A smooth balloon-shaped glass envelope narrows into a neck and sits on two stacked horizontal bands that stand in for the screw base, finished by a small rounded contact underneath. With the glass left empty, it reads as an idea, a tip, inspiration or lighting itself, and works in hint callouts, onboarding tips, energy saving pages, product feature grids and pitch deck headers.
The proportions are tall and clean, the bulb occupying roughly two thirds of the height, with no filament detail so the interior stays free for a number, letter or spark overlay. It pairs with brain, rocket and gear icons in an ideas set. At 16px, merge the two base bands into one.
This is the solid black filled version of the bulb 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.
