Car alarms became a common street sound after electronic vehicle security systems spread widely in the 1980s and 1990s, using a mix of siren tones and horn pulses designed to be impossible to ignore. This short looping version has been shared on soundboards and in video edits because it is instantly recognisable without any context. Creators use it as a shorthand for theft, vandalism or a clumsy accident, and its repetitive pattern makes it useful for pranks, gaming clips and short comedy videos online today.
