Could you run rock lights in series ~ Meaning can you run 1 Positive around the vehicle and ground each light as you go or also run the ground around @ the same time and tap into it @ each location ? I do plan on running a relay & fuse between them. It seams most run individual Pos/Neg wires from each light to 1 main at the relay and end up with a good amount of wires to connect @ the relay. Any draw backs to running it in series and can it be done that way ?
