The ditch lights are LED's, a 1K resistor and a 9V battery will test them. Pull the connector from the board and power them from the battery through the 1K resistor. If they don't light one way, reverse the connections. If the bulb is bad, it won't light with either polarity.

With a 1k resistor and 9v both will light up with positive to gray and negative to black. This is obviously with the connector removed.
