Bull894 Posted December 12, 2021 Share Posted December 12, 2021 I have my 22 F250 exactly one week today. We had alot of rain yesterday all day. Today it is sunny out. I noticed that both front headlights have fogging/ moisture in them. Has anyone else experienced this? Going to contact the dealer on Monday.

Jim58 Posted December 14, 2021 Share Posted December 14, 2021 I talked to a guy last week in Alaska. His LED headlights were full of ice. Ford replaced them at about $2000 per side. Quote Link to comment Share on other sites More sharing options...
ThatGuy509 Posted December 17, 2021 Share Posted December 17, 2021 I hope it was out of Fords pocket and not his own!!!! Quote Link to comment Share on other sites More sharing options...
o4ep3civ Posted January 5, 2022 Share Posted January 5, 2022 (edited) I’ve seen this happen a lot. And ford will replace them. Edited January 5, 2022 by o4ep3civ Quote Link to comment Share on other sites More sharing options...
OsideF250 Posted January 5, 2022 Share Posted January 5, 2022 I’ve read in other places that this is common. You would think that if enough people have complained about it, Ford would look into fixing the issue and getting it right from the beginning.

The seal from the bulbs/led connector? Or from the plastic melted seams in the housing assembly? Quote Link to comment Share on other sites More sharing options...

My 1993 Explorer had a problem with the seat rails causing the driver’s seat to rock back and forth. They’re still having that same problem on a few vehicles today. Some things are either too hard or too expensive to fix properly. Quote Link to comment Share on other sites More sharing options...
FL Lariat Driver Posted January 7, 2022 Share Posted January 7, 2022 The 2022 SD owner's manual page 118 talks about how much condensation is acceptable in the headlight, how long it might take to clear and when to contact the dealer.

Correct - some moisture is normal but it should clear quickly. Quote Link to comment Share on other sites More sharing options...

IUEC135ELEVATOR Posted January 9, 2022 Share Posted January 9, 2022 (edited) Condensation in headlight makes sense and even more so with larger volumes. Very much like a gas can when you put the lid on after it is sitting out in the hot sun. When the air inside it condenses and if there are no air leaks it will pull the sides of the can in. OR... If you have even the slightest micro leak in the cap it will not pull sides in but will suck air in from the outside, and outside air has humidity. The larger volume of air inside of a sealed system is more air to condense down. If all seals are perfect and wires going into plug are sealed and there are no cracks or defects where the plastic seams are welded then you will get no moisture in the headlight after cooling has occurred. But then you will have some serious contraction of the plastic housing. Which is probably why you see a lot of headlights that have microfractures all through the plastic, especially more so the older they get and being sun-baked for 5 10 15 years (plastic becoming more brittle and still expanding and contracting). These headlights have a lot of clear frontal surface area that will be highly susceptible to deflection.? I would imagine people that live in Arizona would have less issues with moisture in headlights then somebody that lives in Washington state because of the humidity in the air. I expect to see F series 2017 through 2022 headlights that are either riddled with plastic cracks / microfractures, or somewhat cloudy film from the inside from intake and exhaust pressure differences. Think of your headlight as a gas can or a car tire with heating and cooling differences and pressures. Something will always give unless it is designed not to give. I am curious on the pressures involved. When you have large volume headlights that is perfect and has no defects and you put a new bulb in it when it is 10 - 20 degrees outside the air inside will pressurize and blow out past the seal, then your assembly from that point on would be at a vacuum. I guess it would be best to always change your headlight bulb in somewhat of a neutral dry temperature if this is actually what is going on inside of a headlight. I am going to do a little experiment and get a large volume headlight 17-22 (to be exact), make sure it is sealed perfectly and then start running it through the sequences of heating and cooling just to see what the pressures are.... JUST OUT OF PLAIN CURIOSITY! ???There is a mathematical calculation to see the exact pressure volume/air density/temp..... I will see how close that is to actual pressure.

IUEC135ELEVATOR Posted January 9, 2022 Share Posted January 9, 2022 Would cool to see statistics on how headlights hold up in different parts of the country and when failure occurs what is the reason for their replacement. They say all your questions will be answered if you go to heaven. They're going to look at me like I'm nuts if I ever go there because I'm not going to be asking questions about the answers of the universe I'm going to ask 500 questions on trivial statistics. :Enter into pearly gates.... ME: can you show me headlight replacement statistics for all vehicles around the world. How many peanut butter and jelly sandwiches have I eaten, where exactly is Jimmy Hoffa buried, what's up with that park in the driveway but you drive on the parkway naming, where did ants come from...ect ect..? Pool angel fella that answers questions: WTF? REALLY?? ME: yes really and I have about 10,000 more.? Poor angel fella: crap,another one of these guys, this is going to be a long day!?

The headlight assembly is NOT hermetically sealed. In other words, it has vents that allow for inside and outside pressure differences to be equalized immediately. Otherwise the headlight would expand and contract and suffer cracks and other failures. The moisture inside the headlight is a byproduct of the vents but the vents will also allow the moisture to dissipate. Quote Link to comment Share on other sites More sharing options...
menasco Posted January 9, 2022 Share Posted January 9, 2022 I'm guessing here but the LED lights generate no heat whereas the incandescent do and probably allow the moisture to vent. I bought LED replacement lights for my 97 Jeep TJ. I recall there being a discussion about using them in winter climate because they would not melt the snow/ice. My 15 F150 Plat w/ LED does not have this problem and I assumed there was something inside to heat them. Quote Link to comment Share on other sites More sharing options...

So are the people with headlight moisture on THESE truck having a venting issue or would it be outside environment? If these have vents then if the vents were stopped or restricted? It is obviously not a design issue... quality control or blocked vents then? just curious? Just came in from outside, while out in the barn and carport.. I looked at some lights I could get to, fog lights for scion, headlight for chevy truck have on shelf, led light bars on tractor and led headlights for tractor and led light bar on workbench going on truck. None of them have any vents. Is it just large volume headlights that have vents? Or is it only large assemblies with halogens are vented...not led or low volume like my Chevy headlight....

FL Lariat Driver Posted January 10, 2022 Share Posted January 10, 2022 I can't speak to all types and sizes of headlights and auxiliary lights but the 22 Super Duty Owner's Manual page 118 specifically mentions headlight vents and moisture. I would suspect that folks having moisture problems in LED lights or even halogen lights are experiencing just the right combination of humidity and temperature to cause condensation and/or they have an actual defective housing that isn't allowing for proper ventilation. I have LED lights on my 2018 F-150 and I live in Florida with lots of high humidity, but I've never seen any amount of moisture in my housing that didn't go away within a day or so. I wouldn't think that the size of the housing would make any difference because the housing still has to be vented to the outside in some way, however subtle, to prevent the expansion and contraction and the housing isn't designed so it can be submerged it just has to be mostly waterproof.

IUEC135ELEVATOR Posted January 10, 2022 Share Posted January 10, 2022 (edited) Makes sense being led...I would imagine the heat generated is much much lower than halogen or hid. Harder to evaporate... That may be why light bars don't have vents....they don't heat up enough.

I do know that mercedes headlights have vents because the owner of the company that designs and manufactures them told me he supplies them to mercedes. So its not just large volume headlights with halogens Quote Link to comment Share on other sites More sharing options...
Gpf2ez Posted January 13, 2022 Share Posted January 13, 2022 This is actually addressed in the manual and it is normal. Quote Link to comment Share on other sites More sharing options...
Gpf2ez Posted January 13, 2022 Share Posted January 13, 2022 Why is there condensation in the headlamps? Headlamps have vents to accommodate normal changes in air 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 fine mist can form on the interior of the lens. The fine mist eventually clears and exits through the vents during normal operation. How much condensation is acceptable? The presence of a fine mist, for example no streaks, drip marks or large droplets. A fine mist covers less than 50% of the lens.
