Outline light bulb with rays radiating around it and a ribbed screw base
About the Lightbulb color outline icon
A rounded pear shaped bulb sits at the center with eight short straight rays radiating evenly around its top and sides, showing it switched on, and a ribbed screw cap with a small contact tip below. It stands for ideas, insight, innovation and helpful tips, which suits brainstorming boards, hint and tooltip buttons, startup and pitch decks, energy saving pages and dark mode or lighting toggles.
The rays are drawn as separate detached strokes at even angles, leaving clear space around the glass so the outline stays crisp, and the base uses three stacked bands for the thread. Pair it with brain, rocket and gear icons in an innovation set, and keep the rays at 32 px or larger so they do not merge into the bulb.
This is the colour outline version of the lightbulb icon: the same line drawing in an accent colour, useful for highlighting a state, a category or a brand tone without adding visual weight.
