What is your target volt and amp draw to feed the LEDs?
I can figure out the resistors you need.

My target voltage is 12.4 as I tested them for a while at that voltage and no problems. My target current is 131mA. That's what 1 of them draws when connected to a fully charged 12v battery outside of the car, same one I tested on and none of them burnt out.
