HID Battery Harness and Relay for H4-3 Bi-Xenon Kit


  This HID battery wiring harness is a required loom that powers a H4-3 Bi-Xenon HID kit directly from the battery.


 The Harness protects your car’s electrical system, it also prevents drawing a higher current than it can actually provide. This ensures full voltage stability for your  HID kit and the car electrical system. The harness also comes with a built in fail safe fuse.


(Loom plugs directly into existing vehicle headlight plug)


NB. Some vehicles may require additional length adding to positive wire depending on vehicle battery location!
