1. A harness kit for emergency lights, comprising:
a junction box;
a power cable extending from the junction box;
a first light cable extending from the junction box, wherein the first light cable comprises:
a proximal end extending from the junction box; and
a first modular connector disposed on a distal end of the first light cable,
wherein the first modular connector is configured to connect with an emergency light; and
a second light cable extending from the junction box, wherein the second light cable comprises:
a proximal end extending from the junction box; and
a second modular connector is disposed on a distal end of the second light cable, wherein the second modular connector is configured to connect with an emergency light;
wherein each of the first light cable, second light cable, and the power cable comprises:
a ground wire;
a signal wire; and
a first function voltage wire,
wherein the junction box includes:
a ground circuit path connecting the ground wire of the power cable with the ground wires of the first and second light cables;
a first voltage circuit path connecting the first function voltage wire of the power cable to the first function voltage wires of the first and second light cables; and
a signal circuit path connecting the signal wire of the power cable to the signal wire to at least one of the first and second light cables;
wherein the power cable comprises:
a proximal end extending from the junction box; and
a third modular connector is disposed on a distal end of the power cable;
a controller, wherein the controller comprises:
a switch box;
an input cable extending from the switch box;
an output cable extending form the switch box, wherein a third modular connector is disposed on a distal end of the power cable, the output cable has a fourth modular connector at a distal end, and the fourth modular connector is connected to the third modular connector;
wherein each of the first light cable, second light cable, the power cable, and the output cable of the controller comprises:
a ground wire;
a signal wire; and
a first function voltage wire; and
wherein the input cable comprises:
a positive voltage wire; and
a ground wire.
