Red Signal Flag with Black Triangular Cutout - Nautical & Safety Symbol #3062209 (License: Personal Use)

The image displays a vivid red rectangular flag with a black isosceles triangle removed from its right edge, forming a pennant-like shape. This design matches the International Code of Signals flag "K" (Kilo), which signals "I wish to communicate with you," though visual variants exist in safety and military contexts. Its high-contrast color scheme ensures maximum visibility under varied lighting conditions.

Commonly used in maritime navigation, emergency response signage, aviation ground operations, and graphic design as a universal warning or attention-grabbing symbol. Matches user intent for identifying signal flags, safety icons, or vector assets for UI/UX design.
