my son put amazon leds on the xj before we got it and they had the halo option, like the second amazon link on the first page. not those exact ones but similar
they are stupid bright. like unbelievably bright but they light up everything from the ground right in front to the tops of the light poles on the side of the road. the direction is horrible and blinds anything in front of the jeep. hi and low settings look identical on these headlights, so that tells you how bad the reflectors are.
i had to put some film on the tops to cut down on blinding everything in front of the jeep on the road at night or in the morning.
i did the relay conversion on my yj and i think that would be the best thing to do to the xj. it was night and day difference on the yj so i imagine it will be the same on the xj
