The plug can be broken internally as well as clearly failed like a light bulb. If any plug goes bad (open, or open under load only) the remaining will not show power at all. If they are OK, a Volt meter, or test light will show dimmer light toward the last plug as the voltage approaches 1 or 2 volts in the last series plug. I suspect the first plug is bad as there would be visible (full brightness shown on every plug until the test found the broken plug. The light would be bright because the system is not loaded to ground and thus the plugs will pass near full voltage to the test light. Going with the newer style plugs is best policy for reliability.
