1977 172N Panel LT knob

[OkieAviator]

I'm looking for a part number for the knob that controls my instrument and radio dial light rheostats. Found a panel picture of another 172N and circled the part I'm looking for.

The actual rheostat works, I just need the knob the thread on to make it easier to use.

Appreciate it.

Rheostat = S2091-5
Knob = S1995-5
Light Dimmer Knob - S1995-6

Rheostat controls two sets of lights in some cases is why 2 knobs. I found a stock at cessnaparts.com, a bunch of them on controller.com.

If you ever need the bulbs:

red map bulb (12V) is S1876-3
white light bulb (12V) is S1876-1

I guess Aircraft Spruce sells this as well, just in case:

Thanks!

I bought the knob on Ebay for $8.50... the inner knob part is over $100.... I might just set that with a screw driver and not touch it again...

Buddy, that sounds like a plan right there! Stupid aviation parts.
