摘要： A rural mailbox signaling device actuated by opening of the mailbox door. A brightly colored signal rod is pivotally mounted along the top surface of the mailbox and biased in an upright position by a spring. A locking pin is pivoted at the distal end of the signal rod and is swung to a right angle position when setting the device. The door is closed and the signal rod forced against the spring to a horizontal position. The locking pin is swung to a coaxial extended position engaging a hook member attached to the door latch which holds the signal rod horizontal. When the mailman opens the door to deposit mail, the signal rod is released and flips to the upright position.
