About the Solution Bulb Question Mark black outline 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 black outline version of the solution bulb question mark icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
