yeah LED's are supposed to have a long lifespan, but they do blow out. Pretty much every LED i put in my car is out right now. You can see about getting whatever board they are attached to replaced from dell, or you can take it apart and solder in a new one...but considering the effort involved, i'd just live with it.
