FSYLX 2pc H4 bixenon adapter Hi-Lo Relay Wiring Harness HID Xenon Ballast Cable Wire Connector for One Auto Motor Headlamp Light


Why we need to add a H4 wiring harness?


This harness help to connect with H4 car headlight directly, no need to change the car circuit, good to protect the car circuit, making it more stable and strong. The starting current of HID is very big, however, most cars’ circuits are designed according to halogen lamp, thus the circuit line is too small for HID. In such situation, if you don’t add a hid relay wiring harness, it may cause two lamps can not start or even worse--burn the auto PC!!


It can be used both in H4 car headlight and motocyble.


Package Include :


2pcs  H4 Hi-Lo Relay Wiring Harness(not include the bulb and ballast )


H4 HID cable_23418
