History Main / AlertnessBlink

* In ''VideoGame/TheLegendOfZeldaTheWindWaker'', the old man on Windfall Island who asks you to look for his daughter makes the sound and flashes the symbol every time you get in range for him to ask you again. Can reach MostAnnoyingSound levels, since he stands right outside the entrance to the main part of the island and you'll have to tap though his dialogue if he gets close enough to you.

* The late 1970s ''{{Spider-Man}}'' series starring Nicholas Hammond actually managed to pull off a live-action version of this trope to indicate when Spider-Man's spider sense went off. They'd intercut photo-negative images with the color-corrected images for a few seconds, creating the same effect as a standard Alertness Blink.

* ''KimiNiTodoke'' uses this every so often as well.

* ''KoeDeOshigoto'', almost always followed and/or proceeded by LuminescentBlush due to the {{ecchi}} nature of the series.

* Both guards and civilians in ''VideoGame/Payday2'' do this with a "!" symbol over their heads during stealth mode, to indicate that they've spotted something that has alerted them (dead bodies, loot bags, a player). Players only get a sound effect for it if they're the one who caused the alert state. They will also show a "?" over their heads if something is within their field of view but has not yet alerted them.

* The second MinamiKe season has the "!" version.

* This happens a few times consecutively when [[Anime/LuckyStar Konata]] realizes the chocolate is oozing out of her cornet.

** ''Anime/ExcelSaga'' features a Newtype Flash in the episode parodying ''{{Gundam}}''.
