When your high-beams are off, the shield is covering part of the bulb which prevents it from going higher than ~4 feet (this places it just below the rearview mirror of the car in front of you). When you turn your high-beams on, the shield is removed and the light is allowed to scatter much higher, giving you increased visibility.
The noise you hear is the mechanical shield shifting back and forth over the path of the light.

Thanks for the information. Does yours make the loud noise also? it kind of sounds like the cars with the pop-up lights. As far as i remember it never did it before
