Thetford parts reference
Thetford 636081
Indicator Light-AC
636081 is the Thetford part number for the indicator light-ac. It is printed in Thetford’s own parts documentation, which we hold a copy of and link below.
Thetford says to use 638591 instead
Thetford marks this number with “USE 638591” on its own parts list, which is the manufacturer telling you 638591 is what to order now. That instruction comes from the document, not from us, and not from what sellers happen to call the part.
Current number: 638591
Which parts lists carry this number
It appears on the parts lists for 2 different models: N180 Series and N305 Series. A number shared across several models usually means the component was carried over between them, which is useful when the exact list for your model is not the one you can find.

What we have not checked
We can show you that 636081 is a real Thetford number, what Thetford calls it, and which parts lists carry it. We have not verified that it fits your camper. That depends on your model year, build date and what is actually installed, and we do not publish a fitment claim until we can show it in the manufacturer’s own document.
