I hope this isn't too "techy" to be helpful! The indicator is lit by a relay with two coils. The current flows in opposite directions through the two coils to the lamps, so the relay only lights the indicator if the current to the lamps is NOT equal. That's why the manual says to always replace them in pairs. Personally, I think the relay is a bit too sensitive. It seems to require only a small difference to (often incorrectly) indicate a burned-out lamp.
