About the Think Light Bulb black filled icon

A rounded light bulb glows with short straight rays fanning out on every side; the glass dome sits on a ribbed screw base with a small contact tip below. The mark communicates thinking, insight and a new idea, and is often used for green or eco messaging too. Place it on brainstorming tools, tip and hint callouts, innovation slides, sustainability pages, and course or quiz interfaces.

The dome is nearly circular and the twelve evenly spaced rays sit clear of the outline, so the bulb keeps a bright halo even in monochrome. It pairs with brain, gear, rocket and leaf icons across the set. Give it a little extra padding in button layouts so the rays are not clipped by the edge.

This is the solid black filled version of the think light 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.
