Veritasiums light bulb: What happens to lights on the far end of the wires?

[Beamin]

Veritasium is a sneaky bastard and I thought the units in his answer was in seconds which confused me. So what would happen if we put light bulbs at the far end of the wires where they are 1/2c distant from the battery? They couldnt turn on almost instantly like the center light bulb that would break causality, they must be on at their distance in light speed from the battery?

  my brain exploded
