Great products, this takes all the brightness in the 580 series and packs it into a useful beam shape to light up the road rather than the hood and sky.
My h4 high-beams are dim and yellow compared to these lights.
My only complaint is that I guess I got a lemon of a wire. The plastic connector that connects the wires from the light housing to the relay/batter shorted out and melted about 4ft of wire (as well as the insulation of surrounding wires). I was lucky it didn't do any more damage in the engine compartment.
I was wrong to assume that the plastic housing the relay would also contain an in-line fuse; it does not. For all things Jeep, please install this with a fuse between the relay and the battery's + terminal.
Also, the switch for this setup is pretty lame looking if you care about that sort of thing. I now have the switch connected to the relay in the engine compartment in the "on" position and spliced/extended the switch's wire into my dash's factory fog-light rocker switch - zero problems there.
Couldn't be happier otherwise. Out on the backroads I flick these things on and even just the pair of them turn night into day. Plus they look pretty sweet
