Gathered by embittered, former Green Lantern, Sinestro, the Yellow Lanterns manipulate and wield the power of universally coalesced fear!  BOOOOO!  Sorry. The Yellow Lanterns also feature prevalently in the contemporary Green Lantern space odyssey, The Blackest Night!  Measuring nearly 1.25" across, this cute little button features the Yellow Lantern Symbol; the button you wear when it's time to break from the status quo and raise a little hell!  Ok, put down the gasoline.  Just trying to be punchy here.
