Abstract: A mailbox delivery indicator for a standard rural mailbox signals to a resident when the mail carrier has been to his mailbox. When the mailbox door is opened, an actuator arm extends and pushes an active signaling element, causing it to fall by gravity to a hanging position below the mailbox. Once the active signaling element has fallen, a passive signaling element is exposed for remote observation. The active signaling element in the hanging position together with exposure of the passive signaling element indicate to the resident that the mail carrier has been by his mailbox. At this time, the resident can check his mailbox without wasting a trip to the mailbox. After the resident checks his mail, he closes the door and resets the active signaling element to the covering position.
