The line group directly takes power from the battery, and the xenon lamp power does not pass through the original car harness, and is directly powered by the reinforcing wire group. The original line only plays a controlling role, so that it will not have any impact on the original car, and it can also solve the problem that the xenon lamp cannot be started normally due to the aging of the old car. The special line group (also called the power reducer) directly takes power from the battery. There are independent relays and fuses on the line group, which can better protect the original vehicle line, play a role of strengthening and stability, and reduce the impact on the original car switch. Because the HID starting current is large, the original car is designed according to the halogen lamp. In some models, the headlight line of the original car is too small. If the HID is assembled without the wire, there may be a phenomenon that the two lights cannot be started at the same time. Therefore, the enhanced wire group can make the effect of the xenon lamp more stable, the failure rate is lower, and the service life is longer, which can effectively protect the HID xenon lamp and your car.
