With that high wattage resistor (alum with heat sinks), you will be sinking a lot of current through those wires!! ... and you are forcing the diodes to sink more current than they may take. Consider a simple 5V, 3 leg voltage regulator... you can get them at radio shack... you just ground the center pin, apply 12+ volts to the left pin, and you get 5V on the right pin... it is current limited and has a heat sink... then you can simply tack 100ohm (or whatever) resistors to your LEDs.
