3 way light switch with power feed via the light (two lights)
The power, cable C1, joins the circuit at the light fixture F1. Here the neutral connects to the light F1 and is spliced through to light F2. The hot from the power source is spliced through both fixtures and terminates at the common terminal of SW1 via cable C3.
The travelers of each switch are connect together using cable C4 (taped white and red wires).
The taped white wire of cable C3 is the hot to the light LT2 (where the red wire of cable C2 is used to splice the hot to the next light, LT1).
