Motion sensing dock lighting systems are disclosed. An example lighting system for use at a loading dock where a material handling device is used to load or unload a vehicle parked at the loading dock includes a motion sensing system to be spaced apart from the material handling device. The motion sensing system is to provide an operation signal in response to the material handling device undergoing a change in travel direction within the vehicle. The example lighting system also includes a lamp to be operatively connected in signal communication with the motion sensing system so as to receive the operation signal from the motion sensing system. The lamp is to have a first illuminating mode and a second illuminating mode, and the lamp is to switch between the first illuminating mode and the second illuminating mode in response to the operation signal.
