If you do want to do it with a resistor,a 330 Ohm would do for 12v,but use a 1/2 watt min.

|every tut and old post ive read says to do them in parallel though they've never said why. anyone else no of parallel advantages?|
i want to know this aswell!

In parellel, if one blows the rest will still work
I have mine in series and it works a treat

The advantage to doing them in parallel, is that each one will see the exact same voltage and if one goes out, it's much easier to find the one that is bad. Also, any resistors used would not be big enough to produce any noticable heat. I would personally wire them in parallel.

i think anyway?
and for using 5v yellow line u want 100ohm resistor on each led.
i believe the long leg is positive and shoret leg goes to ground. u wanna sodler the resistors to the long legs.

Yellow or Orange = 12V
Red = 5V
Read the rating on your LED and get an appropriate resistor (for parallel) and/or the appropriate number of LEDs (for series).

so if i do parallel, what resistors would i use for the 12v? (NOT THE 5v)
also would it be better just to get brighter LEDs and then use fewer-ohm resistors? maybe put a bunch on in series and not even use resistors at all? i know radioshack sells some really bright green ones--though i forget the specs on them, ill post them here later, i no they're different from the ones on radioshack.com
