That I recall from the original Genesis, there are enough LEDs to cover each port. I do not recall any offers that provided extra LEDs. However, I do not own Gammadin (yet) and do not know if they added extra LEDs. Regarding buying LEDs, the batteries are not too difficult to change out. Concerning LEDs needing replacing, I imagine you have to contact Planet X or the retailer you bought the fig at to get that matter resolved.
