About the Solution, Solve black outline icon

A light bulb sits inside a circular frame with short rays radiating from its glass, and a question mark fills the bulb in place of a filament. The mix of bulb and query says a problem is being turned into an answer: brainstorming, troubleshooting, insight and knowledge. It fits FAQ pages, help center headers, quiz and e-learning apps, consulting slide decks and support ticket screens.

The round border keeps the mark balanced for avatars and buttons, while the ribbed screw base and evenly spaced rays add texture without crowding the question mark. Pair it with plain bulb, lightning and gear icons for a problem-to-solution sequence. At small sizes drop the outer circle so the question mark stays legible.

This is the black outline version of the solution, solve icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.

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.
