I'm a little confused. Is the only difference from your other headlight this one has a hallo and if that is the only difference then does the hallo stay on with the low beam on also ? Or only as a day running light ?

Yes, we have LED's with or without the halo option. The halo is wired separately from the 3 prong stock plug. You can wire it to key on power for a day time running light, or tie into the park and turn signals to operate in conjunction with those.
