Bright Lights Question

Have you ever noticed that when you engage you bright lights that for a breif moment while the blinker is depressed all your lights are on. Is there an override to make this happen whenever you turn on your bright lights?

Cut Ground Wire coming out of Headlight bulb. Attach the ground wire coming out of the bulb to a ground. (I attached the wires under some exsisting screws near the headlight.) (Do this because when you hit your high beams, the BCM (Body control Module) turns the ground to the low beams off, but leaves the power wire hot.)

Which wire is the ground wire? I had heard that there was an aftermarket module to enable this to occurr.
