Abstract: There is provided a vehicle mounted device (1) for connecting the electrical circuit of a towing vehicle to the electrical circuit of a towed vehicle. The device includes a body (2), a towed-side connector, and a towing side connector (3). The device is configured to receive input signals corresponding to the lights of the towing vehicle and to transmit these signals to the electrical circuits of the towed vehicle. The device includes a protection component to isolate the towing vehicle electrical system. The device may be configured to perform a testing protocol. The testing protocol can include a safety protocol that determines whether a towed vehicle is electrically connected to the device. The testing protocol may also test the functionality of the electrical circuits for the towing and towed vehicles.

Abstract: A jockey wheel includes at least one ground engaging wheel; a mount for mounting the jockey wheel to a frame of a trailed vehicle; a jockey wheel post carrier for carrying a jockey wheel post; a coarse height adjuster for coarsely adjusting the height of the jockey wheel post, wherein the coarse height adjuster includes a locking selector for selecting a jockey wheel post height, the locking selector being biased into a locking position.

Abstract: An electrical socket is described, which is configured to be mounted on a towing vehicle. The electrical socket comprises a socket body, a plug receiver mounted in the socket body and configured to receive a vehicle electrical plug from a towed vehicle, an illuminated closure mounted on the socket body and movable between a closed position in which the plug receiver is closed and an open position in which the plug receiver is accessible to receive the vehicle electrical plug, the illuminated closure comprising a lens and a light source mounted adjacent the lens and configured to direct light through the lens toward the towed vehicle when it is connected to the towing vehicle wherein the light source is also configured to illuminate the plug receiver when the closure is in the open position.
