About the Siren black outline icon
A rounded dome lamp sits on a wide rectangular base, with five short beams shooting up and sideways to show the light is active. It signals emergency, alarm, urgent attention and rescue response. Fitting for police and ambulance service pages, fire safety material, incident and on-call dashboards, security alarm apps, and alert banners that need a stronger cue than a plain bell.
The dome is a half capsule roughly twice the height of its base, with the radiating strokes spaced evenly around the crown so the glow reads at a glance. It works alongside fire extinguisher, megaphone and warning triangle icons. At small sizes drop nothing but the outer beams stay legible from 24 px up.
This is the black outline version of the siren 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.
