Exterior Lighting: Headlamps
WARNING: This page is about a different car, the 2012 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.
The headlamp system is a dual-beam pattern system and consists of replaceable low/high beam bulbs.
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.
