I am thinking that it's more the quality of the LED's than the voltage that causes issues... We have a 2017 surveyor with factory a installed LED strip which has already been replaced under warranty. About 20 LED's burned out within the first week of owning it, the new one is ok so far... Had a good quality aftermarket strip on my previous trailer which had no issues with burned out sections ever.. I've tried different interior LED's in several trailers and campers and found that the quality LED bulbs had zero issues while the cheap Chinese E-bay bulbs were hit and miss. Many of the cheap ones either burn out all together or flicker annoyingly after a while.
