Pyrotechnic signal

A pyrotechnic signal is a type of visual or auditory indicator created using controlled chemical reactions in fireworks or flares. These signals produce bright flashes, colors, or loud bangs to communicate messages, alert others, or mark specific moments, especially in emergency or maritime situations. They work by igniting specific compositions that generate intense light, smoke, or sound quickly and reliably, making them effective for signaling over distances where other forms of communication might not be practical.
