Instrument lighting for 1980 Cessna 182Q [Club maintenance]

So I've taken on a project for my club, as a part of my desire to get more
involved in the maintenance side of things. I'm to seek out options for
new and improved instrument lighting for one of our aircraft.

The club Maintenance Chief provided me with some information he'd already
collected. There is the "post lighting" option which could have come with
the airplane originally (but did not in this case). I assume that this
could be added on after the fact.

There are vendors Aircraft Spruce & Specialty, Nulite, Fiberlite-Aircraft,
and UMA instrument lighting. At least, I think these are vendors grin.
They might actually be the names of the "lighting systems". I'm starting
from scratch, in the sense that I know nothing.

For example, what is "post lighting" laugh?

Anyway...anyone with suggestions for instrument lighting? Vendors I should
contact or avoid? Questions I should ask?

The timing of this is, I think, pretty good. I'll be at AOPA's Expo, and
this gives me a project. But I hope to learn something about the subject
before then.

Thanks...

Andrew
