I just purchased a home built in 1984-1985. I have some new ceiling lights that are to be used for 90C wire only. I understand that all homes built after 1985 are required to have 90C rated wire but since this one on the fence, what is the easiest way to look at the house wiring and determine if it is 90C or 60C rated?

Re: Wire Temperature Indicators
See what happens when you read the instructions?
If wired with "romex" or NM cable, look at the jacket, it will say NM-B. Also the conductor insulation is slightly smaller if its 90 deg C rated, you can best tell by comparing to new NM cable.

I knew right away you were not an electrican, you read the directions. If you are having a hard time trying to determine if the conductor has the proper rating, it is worth calling a 'Qualified' electrican. You did two things right by the way, 1. you read the directions, 2. You came to this forum as opposed to the likes of some of those 'home' forums. The answers there can be unbelieveable.
GOOD LUCK

Re: Wire Temperature Indicators
In reality, the 90C on the fixtures are simply a CYA ploy by the manufacturers. The common argument is that this is due to added heat transfered to the conductors from the lamp/s.
How does this happen on a chandelier marked with the 90C conductor requirement and the lamps located quite a distance away?
Anyways, I go for true antique fixtures, this means I rework them to my satisfaction and won't have a manufacturer to sue in the case of a fire, which is the bottom line to this issue. I must say I agree with manufacturers guarding themselves in our law suit happy world.
