You can make the circuit you need yourself, once you figure out the wiring.
At the home location, connect a 110 Vac relay, whose coil is in series with a 0.5 uFd capacitor, across the T & R of the line. Send whatever low-voltage flavor you want, from a wall-wart, via the relay contacts and the inside wiring. At the distant ends, install a lamp of the appropriate voltage and brightness.
Total cost of the whole thing, less than $20.00
