    Abstract: A message insert includes an insert retainer and a set of alpha numeric characters. The message insert is preferably fabricated from a plastic molding. The insert retainer is preferably fabricated from a rectangular tube. The insert retainer is long enough to allow a cross bore to be formed in an end thereof. The cross bore allows a retention pin to be inserted through the trailer hitch receiver and the insert retainer to retain the message insert relative to the trailer hitch receiver. At least one edge of each alphanumeric character is joined to an adjacent alphanumeric character to form the message. A front of the insert retainer is joined to a rear of at least one alphanumeric character of the message. The front of the insert may or may not be covered.
