Patlite is a Japanese company known for industrial signal lights and stack lights, and the name in this clip points to that bright, signal-style sound rather than to a song or a film scene. Kiran kiran is a Japanese word for sparkling or twinkling, which fits the light, glittering character of the tone. Online, short alert tones like this are shared as reusable sound effects for edits, much like a ding sound effect or a Discord notification, because they signal attention without needing words. Their continued use comes from that simple, instantly readable cue.
