Ford Motor Company (Ford) is recalling certain 2018-2020 F-150 trucks equipped with high series LED headlamps with Autolamp (On/Off) functionality. The Daytime Running Lamps (DRL) may remain activated instead of dimming to parking lamps when the Master Lighting Switch (MLS) is manually rotated from the “Autolamps” switch position to “Headlamps On.” As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 108, “Lamps, Reflective Devices and Associated Equipment.”
