Is there a manual or instructions that tell you the functions of the lights.
Most of the time LED's used for indicating AC power, use a full wave rectifier to convert the AC to DC so there's no flicker during the second side of the sine wave. If that's the case, then it won't matter if the hot or neutral are swapped it'll still light. Though it would make a lot of sense to use a half wave and let it also indicate reversed polarity.
