I already know that you need resistors with the 55w kit because this car needs a relay. I have the 55w kit and they still didnt work. I believe I was one of the first to have this work without issues using a relay harness and resistors. It makes it so much easier. The biggest issue is the factory headlamps do not get enough Voltage under deceleration 9v-9.7v which shuts down the ballasts.
