The others have the thrust of it, here is one more tidbit. With the bulb in, and the lights on, use that volt meter of yours to probe the socket/connection to check for ground faults. use a light bar bare spot, ot thread edge to ground the black lead, then probe into the fixture to look for volts. touch the housing, then the socket, then the exposed brass of the bulb. If nothing shows up, the ground side is probably good. Pull the bulb and reach into the socket with the red probe. If ~6v it should work if not I would check to see if there is a rusty connection at the Plus terminal on the outside. if the volts showing at the terminal are low, and the connection at the switch is clean, I would replace the wire. Connect the new wire to the end of the old one with small shrink tubing (use 2", and heat well to bind them in the tube)then pull/push and curse the new wire into place, crimp on new connectors, and illuminate.
