A vehicular circuit body includes a trunk line that extends in a front-and-rear direction of a vehicle, a plurality of control boxes that are provided on the trunk line, and a branch line that connects the control box to an accessory. The trunk line and the branch line each includes a power line having a predetermined current capacity and a communication line having a predetermined communication capacity. The vehicle is divided into a plurality of regions. At least two control boxes are disposed in the regions which are different from each other, each of which includes a gateway conversing communication methods for the communication line of the branch line and the communication line of the trunk line. A plurality of the gateways are able to communicate with each other via the communication line of the trunk line.

An electrical connector includes an insulating body, a plurality of ground terminals, and a plurality of signal terminals, the latter two of which are fastened to the insulating body. The insulating body includes a base board having a first tread and a plurality of protruding portions extending from the base board. Each of the protruding portions has a second tread and a riser connected to the second tread and the first tread. A portion of at least one of the ground terminals embedded in the base board includes a ground shoulder arranged adjacent to the first tread. A portion of at least one of the signal terminals embedded in the base board and one of the protruding portions includes a signal shoulder arranged adjacent to the second tread of the corresponding protruding portion. Top edges of the ground shoulder and the signal shoulder have a gap there-between.

A low profile lighting adapter can include a first housing section configured to hold an electrical ground connection, and a second housing section configured to couple with the first housing section, the second housing section including a planar surface orthogonal to the first housing section. The low profile lighting adapter can include a second electrical connection disposed in the first housing section and opposite of a first electrical connection, wherein the first housing section is configured to allow individual actuation of the second electrical connection along an axis orthogonal to a planar surface of the second housing section. The low profile lighting adapter can include an extending arm coupled to the second housing section and configured to rotate about the axis. Certain of the disclosed embodiments can permit a live connection to be individually set at different levels to engage different electrical circuits on a light track.

A vehicular circuit body includes a trunk line that includes a power source line and a communication line and is routed in a vehicle body, and a plurality of control boxes that are disposed in a distribution manner along the trunk line. In a vehicle, a first power source supplies power to an accessory mounted on the vehicle and a second power source supplies power which is higher in voltage than the power of the first power source to a drive source of the vehicle. The vehicular circuit body further includes a voltage drop unit that reduces the voltage of the power supplied from the second power source, to the voltage of the power of the first power source. To the power source line of the trunk line, the power from the first power source is supplied, and the power from the second power source is supplied through the voltage drop unit.

A vehicular circuit body provided in a vehicle, includes: a trunk line that extends in at least a front-and-rear direction of the vehicle; and a plurality of control boxes that are provided in the trunk line, in which the trunk line includes power source lines of two systems and a communication line.
