About the Bulb black outline icon
A pear-shaped glass bulb encloses a visible filament held by two support wires that narrow into a stem, and below it a threaded screw base with ridged rings and a contact tip. It carries the familiar meanings of a new idea, insight, innovation and electric lighting, plus literal use as hardware. Use it in tips and hints panels, brainstorming and note apps, energy saving dashboards, hardware store catalogs and pitch deck slides.
Detail concentrates in the center, where the filament coil and support wires add texture against the smooth outer glass curve, while the base is drawn as four stacked bands that read as threading. It pairs with battery, plug and power icons. Since the internal lines are fine, use it at 32 px or larger or switch to the filled style.
This is the black outline version of the 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.
