This invention relates to fifth wheel hitches, and particularly to a primary locksecondary lock fifth wheel hitch.
For safety reasons, fifth wheel hitches are now required to have a secondary lock as well as a primary lock.

Because of this, an inexperienced operator might become confused as to whether the hitch is fully released during uncoupling or fully secured during coupling.
