I don't have an issue. OP, does. I was just saying that if our cars have the wrong resistance for the lighting; it can blow fuses. And that the ohm load of an incandescent bulb is much higher than an efficient LED. (or group of LEDs in series)
You can direct hook 4 three volt LEDs in series to a 12v circuit. But, the voltage to our cars jumps to 14.5v when the car is started. Thus the need for a resistor, so as not to overdrive the (small) LEDs I am using. I 'm using 18 5mm LEDs in a series / parallel configuration with a resistor in one location. I have different configurations in different locations.
