ABSTRACT:
A signaling device that visibly indicates that the door of a mailbox has been opened. During operation, a signal flag is held in a generally vertical or elevated position by the door of the mailbox which remains closed. However, upon opening the door, restraint on the signal flag is released, thereby causing it to pivot downwardly and come to rest adjacent and atop the mailbox.
