I was sitting in my car and was messing around with all the features and I got to the highbeam and after turning highbeams off, I heard noise (driver door was open and the noise came from under the hood). So I get buddy and tell him to turn on/off highbeam and I stand in front to see where the noise was coming. Noise came everytime I turn off the high beans

So I dont know if this is normal? Can some one else check this out with their car.

Yes, this is normal.

The low-beams are really high-beams with a shutter over the top half.
The noise you are hearing is the mechanical shutter lowering into place to block off the high-beam portion of the light.

HID (HIGH-INTENSITY DISCHARGE) HEADLIGHTS

Previously, the TL had HID (High-Intensity Discharge) low beams coupled with conventional halogen high beams. The new TL headlights feature HID high and low beams, as well as built-in fog lamps. These bi-function HID high/low beams are made possible by a shutter device that mechanically controls the light output of the HID unit. When the driver selects high beam, an electric solenoid in the headlight moves a shutter forward, opening up a greater reflector area inside the headlight. When the lights are operated on low beam, this shutter repositions to act as a cut-off to keep the lighted area closer to the vehicle.



That device makes noise.
