How Did We Miss This One?? The Idea Bulb is a visible indication to the audience that someone has had a bright idea. Sometimes, though, the idea will be a sound notion, so we hear the Idea Ding. It's a simple one-note Sting sound made on a xylophone or glockenspiel or something else that sounds light and metallic. Often appears with its Sister Trope Idea Bulb. Also related to Audible Gleam. The same sound is often used for Love at First Sight, but that's a different trope. Seen It a Million Times.
- UHF, when George("Weird Al" Yankovic ) gets the last-ditch idea to hold a telethon for his TV station.
- Dexter's Laboratory: The Monkey episode "Peltra" has the Idea Bulb and Idea Ding happen together as Agent Honeydew thinks of a way to save Monkey.
- Happens frequently on Phineas and Ferb -- not quite Once an Episode, but when it does appear, it's almost always before Phineas' "Hey Ferb!" Catch-Phrase.
- Ultimate Spider-Man: "Venom": Peter is standing alone in his Dramatic Spotlight with no idea how to sort out what to do about Harry's dislike of Peter's "new friends". Along comes Mary Jane with a suggestion that comes with its own Idea Ding. Peter brightens up, heartened by her great idea.
