Typically 5 to 6 LEDs are connected in series. This series string is connected to a final dropping resistor and then the entire series circuit is connected to the +12V battery. Since you only have four LEDs in each spoke, I think you could make a cluster of LEDs in the center rather than a single one.

Take a look at this website for a schematic and some design equations.
