I think the point of the thread was to disable the headlight so it would be running 24/7 with the HID bulb in there, I'm sure some people (such as me) still want parking lights to come on since that's not hurting anything, but want to have control of the headlight bulb, which would be the brown wire removal. If this thread was disabling DRL with no reguards to HID's, then I'd assume the brown wire would be pointless topic.
