About the No Idea Sign Bulb black filled icon
A solid light bulb with a filament and screw base sits inside a bold ring, cancelled by a diagonal bar running corner to corner. It reads as no idea, creative block, a rejected suggestion or ideas not allowed. Use it in brainstorming and innovation slides, writer's-block or burnout articles, feature-disabled states, quiz and hint systems, and error or empty-state illustrations.
The prohibition ring is heavy and the slash cuts across the bulb at 45 degrees, so the negation stays obvious even in one flat color. It pairs with the plain light bulb, idea, question mark and warning icons. Use the crossed bar at full contrast; at 16 px it can blend into the bulb outline.
This is the solid black filled version of the no idea sign 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.
