Yeah, it's for the whole instrument cluster, even the bulb's that are in them. I really don't know about the usage of them. I guess you could ask some of the experts on this site. I have asked them things, and got very good answer's that worked.

But I have 4 or 5 of these units now, I don't know the mileage on the newer ones, but you want one very close, if not the same as your old one. Fairness and right doing is always good.
