A hitch ball-type trailer coupler having a coupler body defining a cavity includes first and second indicator pin guides slidingly receiving respective indicator pins. Each of the indicator pins is slideable between extended and retracted positions, and biased to the retracted position. The coupler is configured for use with a correspondingly-sized hitch ball. Insertion of the correspondingly-sized hitch ball fully into the cavity causes both of the first and second indicator pins to be extended by at least a predetermined amount. Insertion of an undersized hitch ball into the cavity does not cause both of the first and second indicator pins to be extended by at least the predetermined amount.
