The LEDs I see on the board don't light up when I plug them in. How do I make them work?

Question

I see LEDs on the connector boards but they don't do anything. How do I make them work?

The LEDs need to have a series resistor chosen and soldered into place to activate the indicator feature. Consult the applications section of the user guide for the connector boards for information on resistor values.)
