Yes, most of the new cars have gone to a CAN bus system. So there are central controllers in certain locations and they work like switch panels, so you can send a low voltage signal from your switch/button/knob and have the controller near the lights turn them on vice running a power wire through the switch like in your house.
Wiring gets smaller, you have more flexability, and really you reduce the number of wires vice if you wired it conventionally.
