Some cases (such as yours) provide two leds for two hard disks - I don't (off the top of my head) know if any mobos support this feature though.
If you are feeling clever/have some time to kill, you could wire them together in parallel and get them both to light up. On second thoughts, I'm not sure that the mobo would be able to handle the increased current draw, so that may not be such a good idea.
