About the High Voltage Warning Triangle black filled icon
A warning triangle containing a downward arrow-headed lightning bolt, underlined by a short horizontal bar and enclosed in a thin circle. It is the standard mark for electric shock risk, live equipment, restricted power areas and do-not-touch zones. Use it on substation and plant signage, machine labels, utility apps, safety training decks and electrical product documentation.
The bolt runs corner to corner inside the triangle with even gaps from each side, and the rule beneath grounds the whole composition inside the ring. It pairs with hazard, flammable, no-entry and grounding signs. Keep it above 24 px so the arrowhead and bolt notch stay readable.
This is the solid black filled version of the high voltage warning triangle icon: a bold silhouette that reads clearly at 16-24 px and on dark or busy backgrounds, and prints well in one colour.
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.
