Ahhh, I get where you are coming from, but I just can't wrap my head around those brush car washes up here in winter loaded with frozen brush bristles, road sand, salt, de-icing brine and lots of other things most environmentalists would have a shit fit over if they knew.
Led's are dc devices. A 120v led bulb is a group of multiple led's which vary in number to provide different luminosity. A cheap AC led say with 7 led elements flashes from off to on to off and staying off while wave is negative. More prone to flickering when on some types of dimmers. Flicker free LEDs will have a second string of elements that are wired with reversed polarity so they are flashing out of sequence with first string. All that turning on and off is hard on the element. If you have led bulbs you should definitely have whole home surge protectors as well as soft start capacitors on things like air conditioning compressors (higher quality ones may come with easy on designs).
Someone a short time back posted how he dismantled his headlight housing made his change (I don't remember what) and put them back together.In most cases, you won't reach the 50,000 hrs theoretical service life (LED half-brightness life). We've all seen new to 15 year old "one-eyed" vehicles with failed LED headlamps or running lamps.
The likely failure will be the power/current regulating part of the headlight; heat cycling, high ambient temps, surges in the 12v power supply (i.e. jump starting with headlights on), solder joint failure (heat and vibration), ceramic cap cracking, tin whiskers on lead-free solder joints...
The second likely failure will be an individual LED; heat cycling and vibration compromising the tiny wire welds or attachment pads, within the encapsulated LED package.
Although Ford doesn't release test data, am guessing closer to 10,000 hrs MTTF. Or 5 to 7 years of headlight run time.
This suspected stat, and decades experience with LED illumination, is also why I disabled daytime running lights right away (U.S. vehicles, only I'm told).
I am hoping by the time a headlight fails, there will be robust, cost effective aftermarket choices. Or, I can do surgery on the headlamp.
I see non-functional OEM LEDs on vehicles almost every day. All fairly new vehicles.
I agree. I've seen a good many fairly new GM vehicles with some out, also recently saw a fairly new F150 with one out, but I can't say 100% they were LED's, but if I was a betting man I'd bet they were. All have been very recent body styles.
Not so, I just saw some on sale for 999.00And the plastic type that automakers use, might be by design.
I had an F-150 for over 20 years of sitting in the sun. The clear headlight lenses turned to a frosty yellow color (not nearly as bad as Toyotas do, though). I finally bought a replacement set of headlight assemblies for it online. $50 for a pair - including the Halogen bulbs. Someone posted on here that the Maverick's headlight assemblies are over $1K each.
You might also try adjusting the headlights per the manual. Some folks say the OEM headlights are horrible, while others think they are great. Other than the cleanliness of the vehicle, aim is the only other lighting variable between trucks of the same trim level.
Yesterday I saw a pickup with about a 36" LED light bar turned on just before high noon which was attached to hood near the windshield!!!(?).
i'm figuring my leveling kit may have thrown them out.
My 2011 Ford Taurus headlight units were 13 years old when I sold it, and the lenses were as clear as new when that happened. That car sat outside year round in Ontario. They will probably outlast the Maverick.
I'm going to guess that your Ontario sun is not like my Florida sun.
