About the Solution Bulb Question Mark black filled icon

A light bulb with a ribbed screw base holds a large question mark where the filament would be, and eight short rays radiate outward, all enclosed in a thin circular border. The mix of bulb and question mark says a problem is being worked out rather than already answered, which fits FAQ and help-center headers, troubleshooting flows, consulting and service pages, brainstorming slides and quiz or puzzle app screens.

The bulb sits dead center with the rays evenly spaced around its dome, and the outer ring turns the whole mark into a self-contained badge. It works alongside idea bulb, checklist and gear icons in the same problem-solving set. Use it at 40px or above so the question mark reads clearly inside the glass.

This is the solid black filled version of the solution bulb question mark 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.
