H11 Relay used to power any TWO HID kits (LH / RH) from a battery directly.

2 Two ends connect to the ballast
 1 = input signal wire gets signal from original wire harness that went to the bulb
 2 = power and ground can be run to the battery directly

End connector H11 (if wiring to a vehicle with unique connector, you cut the H11 end off and manually wire to your headlight harness)
