I guess it depends on how long it took for them to get that way. LED 
tail lights have been around long enough now that some of the early ones 
have surely racked up a lot of operating hours. Especially on commercial 
vehicles, which can have a very high duty cycle. A three year old 
commercial truck or bus could have as many service hours on it as my 17 
year old van.
