Red Danger Warning Sign Flickers on Gritty Wall

An illuminated rectangular warning sign with the word "DANGER" in a distressed, stencil-like font flickers on and off, casting an ominous red glow. The sign is set against a dark, textured, industrial-looking wall, which reflects the red light. The animation depicts a classic warning light sequence, shifting from a bright, intense red illumination to complete darkness. This unsettling visual is ideal for conveying urgency, hazard, or a critical state in thrillers, action sequences, security warnings, or any project requiring a strong sense of impending danger or alert.
