About the Idea Check Light Bulb black outline icon
A rounded light bulb with a ribbed screw base gives off eight short rays, and a bold check mark sits inside the glass. Together they say the idea works: a solution found, a suggestion approved, a concept validated. Use it on brainstorming and innovation slides, product roadmap boards, tips and best-practice callouts, quiz feedback screens and feature pages about problem solving.
The check mark is what sets this bulb apart from plain or filament versions in the library, and the evenly spaced rays add a glow without clutter. Pair it with gear, rocket and question mark bulb icons. Keep the rays if you have room; below 20 px, a rayless bulb variant stays cleaner.
This is the black outline version of the idea check light bulb 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.
