This 3 wire switch loop satisfies the nec requirement of a neutral in the switch box. You can usually install a light fixture between an existing one and the switch by cutting the cable to the existing fixture at the location of the new one inserting the ends of the cable into the electrical box for the new fixture and pigtailing the new fixture onto these wires.
Wiring A 4 Way Switch
Adding a switch to a light in an existing circuit. One light controlled by one switch and there is no insulation in the wall or stack exchange network stack exchange network consists of 177 qa communities including stack overflow the largest most trusted online community for developers to learn share their knowledge and build their careers.

Wiring diagram 3 way switch with light at the end in this diagram the electrical source is at the first switch and the light is located at the end of the circuit. The easiest way would to be do as you described but depending on the wiring and where the next light is going and the house it might be easier to go from the switch to the other new light but without being there its hard to say. The rated voltage of this switch is 220 250 volts max. This 240vac inline rocker switch can be used to add a switched element into an existing non switched circuit.
Wrap one black pigtail around the other screw and tighten both screws. If i can do it so can you. This is about a 15 min project plus the time it takes to chase the wire took me about 30 minutes to chase the wire. Three wire cable runs between the switches and 2 wire cable runs to the light.
