About the Bulb Zigzag Filament black outline icon
A pear-shaped glass bulb holds a wide zigzag filament supported on two wires above a small stem, and a threaded screw cap with a flat contact tip closes the base. The drawing carries ideas, insight, innovation and electric power all at once. Use it in brainstorming tools, tips and hints callouts, energy saving pages, lighting shops, and startup pitch slides.
Because the filament sits high in the glass, the shape stays readable when the icon drops to toolbar size, while the ribbed base adds texture at larger sizes. Pair it with battery, plug and lightning bolt icons; at 16 px consider the solid version instead.
This is the black outline version of the bulb zigzag filament 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.
