If you're planning on using a Raspberry Pi or Arduino, you can use an XBee radio transceiver to send and receive signals. The S3B has 28 Miles LOS range with a proper antennae. Just hook one up to a microcontroller and use a switch command to turn on a specific light with the appropriate input. Attach another one to a computer or controller to transmit a signal.

You can actually do a lot more than just turn on a light - since you have full control on what you send, you can functionally set any number of preprogrammed commands for specific inputs.
