ABSTRACT:
A service signaling device (10) for a mailbox (20) having a door (14) pivotally mounted proximate the bottom (18) of the mailbox. A signal indicating arm (40) is mounted proximate the lower edge (12) of the mailbox door and moves between set and triggered positions. When the arm is in the set position, and secured to the bottom of the mailbox door (14), it indicates a lack of service to the mailbox. When the mailbox door (14) is opened, the arm (40) moves to its triggered position to indicate that service to the mailbox has been completed. An attachment mechanism (26) serves to mount the signal arm (40) on the lower edge of the door. A catch (54) serves to hold the arm (40) in its set position until the door is opened.
