What could make LED bulbs burn out?
We have a 2015 Keystone 5th wheel. We purchased 18 LED bulbs to replace the typical bulbs in the unit from the factory. Within a 3-4 month period, 14 of the LED bulbs have flickered and burnt out. :( ...

Transients (spikes or load dumps) can definitely shorten the lives of LEDs, especially ones relying only on resistors to limit current. An increase of only a few 100 millivolts forward voltage will cause a large increase in forward current. Short spikes cause cumulative damage to the bond wires and junction material leading to reduced output, increased resistance (and heating) and eventually the junction looses electrical contact and goes dark.
