The hazard
Issue: On certain trucks, there may be a problem with the software that controls the daytime running lights (DRLs). If the DRLs are on, and the light switch is moved to the "ON" (low beam) position, the DRLs do not lower to parking light brightness. Canadian regulations require that these lights switch back to parking lamp brightness when the headlights are turned on. Safety Risk: Lights that are too bright could cause glare for oncoming drivers. Corrective Actions: Ford will notify owners by mail and instruct you to take your vehicle to a Ford or Lincoln dealer to update the body control module (BCM) software.
