Abstract: A position signaling apparatus for indicating desired positioning of vehicle components. The signaling device, including a switch, is mounted to a first vehicle component, such as a tandem axel frame assembly or a portion of the vehicle frame adjacent to the fifth wheel assembly. A trigger mechanism is attached to a second vehicle component. The second vehicle component is adjacent and moves relative to the first vehicle component. The trigger mechanism actuates the switch upon achieving proper alignment of the respect vehicle components. The switch closes a circuit which sends a signal to the vehicle operator upon achieving the desired positioning of the vehicle components.
