Normally when resistor droping voltage to run LEDs off 12v power you are looking for something well under 100 ohms.
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.
