Does anyone know how to replace a LED that may go out
with any of the newer LED tail lights like Dectane? Probably
a rare occurance but may require a complete light assembly
replacement versus simply replacing a bulb with the older units.

 

The leds should last quite a while, but in the event it does go out, I believe you have to replace the whole unit. If you look at the housing, it's completely sealed. That's just from my personal observation
