Abstract
A hitch ( ) with a lock indicator system ( ) interacts with a rotor ( ) to provide an indication that a kingpin ( ) is properly inserted into the hitch. The rotor rotates in response to proper insertion of the kingpin to align a rotor slot ( ) with a plunger ( ). Once the rotor slot and the plunger are aligned, an indicator ( ) moves from a first position, indicating an unlocked kingpin, to a second position, indicating a locked kingpin. A control pin ( ) prevents rotation of the rotor from improper insertion of the kingpin. The control pin is controlled by a control lever ( ).
