It's true that an LED can fail, but it is not the same thing as a normal bulb with a filament. Unlike those filaments that normally burn out after XXX hours of use, an LED typically has an incredibly long lifespan because of the fact that it's not a bulb and does not use a filament. Most quality LEDs (such as those used in '06 and newer 4Runner taillamps) will be more than likely to outlast the vehicle itself. Most "burned out" LEDs I've seen are actually not even bad, but the wiring or connections to them have failed in one way or another. I've seen it so many times, especially in aftermarket spoilers with an LED brake light built into it.
