I have never seen leds expire under normal usage - they are meant to
have 'average' lifetimes in the 10^5 hours. Overvoltage/excessive
current will of course do them no good.
On the other hand, my almost two year old ARMini never had a working
green led from day 1 - there is still a bit of a blue glow from the
strip at one end.
