Exterior Lighting: Headlamps

WARNING: This page is about a different car, the 2014 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.

Daytime Running Lamps (DRL)

NOTE: The Daytime Running Lamps (DRL) are a programmable parameter for this vehicle.

If equipped with halogen headlamps, the DRL system utilizes the existing circuitry and components from the headlamp low beam system. The DRL system operates the low beam headlamps at a reduced intensity.

If equipped with HID headlamps, the DRL system utilizes the existing circuitry and components from the front turn lamp system.

The DRL are activated when the following conditions are met:

the ignition is in run
the headlamps have not been turned on by the autolamp system or the headlamp switch
the transmission is not in park
