While this is true and will likely explain the "Check Trailer Lights" warning, it doesn't explain the issue with multiple circuits being activated simultaneously (indicator and brake circuits tied together somehow). This can sometime occur with a back earth and lamps in one circuit "back-feed" another, LEDs are omnidirectional and shouldn't do this.
