From my understanding, the way the 12's and 13's work (and most newer cars) they send a small signal to the headlights to power them all, if the ECU detects the wrong power usage its sends a bulb out error and powers off the light. When using HID's and this LED kit that are rated below our normal wattage usage, after the bulb out error comes on and the power is killed to the headlight, there isn't enough power to keep the ballast powered on. In comes the use of resistors. They trick the ECU into thinking the bulb is using the full wattage. Which means no bulb out error as well as full power to light. Again thats my understanding so if I'm wrong feel free to correct me.
