WARNING: This page is about a different car, the 2013 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
The halogen headlamp system is a dual-beam pattern system and consists of replaceable low/high beam bulbs.
The HID headlamp system is a dual-beam pattern system. It consists of a single replaceable HID bulb in each headlamp assembly.
The BCM supplies voltage to the headlamps when demanded. If the headlamps are on when the ignition switch is turned off, the battery saver feature turns the headlamps off after 10 minutes have elapsed.
