Turning LEDs on with a spike while disabled

Example:
If no pins receive input, set LEDs to X (Thats Disabled)
If pin 1 receives input set LEDs to Y
If pin 2 receives input set LEDs to Z

You can use any number of output devices to control the lights as part of your custom circuits as long as you are not controlling motors, solenoids, or other actuators I think you are fine.

All you need is a way to get information out of the RoboRIO to the control device and some sort of circuit to turn the lights on/off.

There are tons of ways to get data into or out of the RoboRIO (I2C, UART, SPI, Ethernet, USB, ...) and there are an even larger array of choices for ways to turn the LEDs on/off

Yeah, with SPI output on the RoboRIO, You might be able to eliminate any other circuit or device. I believe you can get LEDs that can be controlled by just SPI.
