I've had my 2018 SCREW for a couple months now and I've been noticing that the headlights tend to fog up quite often especially on colder days. It's mainly the lower half of the headlights. Is this normal?

I am inclined to say no. Perhaps others can chime in. Your headlights should be sealed and if you are getting condensation on the inside (fogging), that means moisture is getting in. I know on all my other cars I don't have fogging issues.

Ten bucks Ford says this is normal as they did on the previous F150 HIDs. Trick there was to throw a desiccant bag in through the parking light bulb hole. I think I had mine like that for 3 years and never saw condensation again.

That's a great idea! I'll try that... my dealership for my McLaren actually did that and that took care of the condensation. Thanks for reminding me of that!

F150 owner’s manual; Lamp Assembly Condensation; ~ page 336 in the 2017 guide,

Exterior lamps are vented to accommodate normal changes in pressure. Condensation can be a natural by-product of this design. When moist air enters the lamp assembly through the vents, there is a possibility that condensation can occur when the temperature is cold. When normal condensation occurs, a thin film of mist can form on the interior of the lens. The thin mist eventually clears and exits through the vents during normal operation. Clearing time may take as long as 48 hours under dry weather conditions.
Examples of acceptable condensation are:
• Presence of thin mist (no streaks, drip marks or droplets).
• Fine mist covers less than 50% of the lens.
Examples of unacceptable moisture (usually caused by a lamp water leak) are:
• Water puddle inside the lamp.
• Large water droplets, drip marks or streaks present on the interior of the lens.
Take your vehicle to a dealer for service if any of the above conditions of unacceptable moisture are present.

That's awesome Smurf. Thanks. Found same on page 89 of the 2018 Owner's Manual. Think I may take it up with the dealer next time I'm in. Pretty sure I noticed streaks and drip marks last time I looked...after earlier noticing heavy fogging in sub zero temps.
