Headlight Defogging and Deicing

With input from temperature sensors, the headlights will defog and deice automatically. Headlight defogging occurs automatically between 41 to 68°F (5 to 20°C) and initializes when the truck is keyed on. Headlight deicing occurs automatically at 41°F (5°C) or lower to melt ice and prevent headlights from icing again.
