That's a lot of light! Must be nice night ridingI have 2 14'' Light bars that I am running, I spliced one into my Low beam harness and on into my High beam harness.
I just tapped into the wires that supply power to the bulbs right behind the headlight housing.
With all stock lights, 2 light bars and LED Halos it has not burnt any fuses yet.
So you should be good to go.
