It seems when new technology is applied to RV's, in this case LED replacing incandescent bulbs, the introduction works well for the first couple of years. However, once it becomes wide spread, in near or all models, the "Bean Counters" go to work locating the cheapest product they can find that is supposed to do the same.
The LED wave really started in 2013 for Newmar. How many 2013 or 2014 owners have had these issues? I for one have not! Not even one failure.

The old saying, "You get what you pay for" probably still applies.

M4 has some replacement units for some of the non replaceable LED lights. Might be something to look into.

I checked your LED light in the 2013 KA catalogue, yours has been discontinued.

But the replacement is the current one for 2018 and 2019 in all coaches good old part number 134551!

When you say "Discontinued", do you mean through Newmar, or do you mean the LED maker no longer makes these?

It shows the catalogue at Newmar as discontinued. My guess it is not likely still made the same way 5 years later....have designed a less costly way to make the same thing.....

High failure rates of LED lighting is in many cases from the LED driver that is being used.
In our older coach 12v is not really 12v. It is goes up and down depending on the chargers state. Early and or cheap LED lights were built to work with exactly 12 volts. Putting 13.5 volts on these could lead the early failure depending on how the driver was built.
I tried to locate specifications on the Sunlight lights Newmar is using but could not locate anything. Only found one reference that stated 12v maximum voltage. If that is the case then early failure would be imminent.

I just replaced two of the lights in my three-month-old 2018 King Aire. I noticed they had a date code of 2017-08-30. The new ones Newmar sent me to replace them have a date code of 2017-10-25. Anyone seen any lights that are newer?

I just looked at the three that I pulled out last week and I donít see a date code on them. Is the date code on the manufacturerís sticker (if so, where) or a Newmar sticker? The new ones did have a Newmar sticker on them, but I didnít take a picture of them before installing.

I did ask them at Newmar. They donít care. ďJust buy a new oneĒ is the answer. In a year I had to replace four already.

Exactly.

LEDs need constant voltage/constant current to operate properly. Quality LED lights have constant current circuitry and will be spec'd for a range of voltage, typically 8-30 Vdc. Cheap LED lights will only be spec'd at 12V and won't survive the ranges seen in an RV.

It's not the LED itself - provide it constant current and it will have long life. The problem is the cheap circuitry connected to it.
