Do you have adaptive bi-xenon headlights? If you do, the upper bulb in the compartment with the AE (angel eye/halo) bulb is the Flash-to-Pass (or DRL if coded). The F-T-P bulbs illuminate when you pull the stalk TOWARD you. The high beam feature is activated when you push the stalk AWAY from you.
The bi-xenon headlamps use a single bulb for the low & high beam. When high beams are called for, a flap moves to allow the bulb's beam to be thrown differently. The bulbs closest to the grills...again, are for F-T-P or DRL.
