Anybody have one of these on their panel and know what it is for?

I am assuming it is original equipment but it has never illuminated since I have owned the airplane, has no label, and it is not mentioned in the POH.

Do you have a older JPI?  They install a warning light in the pilots view.  That is pretty close to where my light is for my JPI 700.

Looks like a prior owner had added a few warning lights in the area...

Some things that get added along the way...

  • Engine monitor exceeds limits...
  • Alternator exceeds limits...
  • Stall warning device...
  • Some other add on got a limit that it wants you to know about...

Factory supplied limit warnings usually are resident in the annunciator panel...

Kind of odd that it didn’t get labeled...

Nothing will cause more un-ease... flying along and having that light turn on, and not know what it means... :)

Might be easy to chase from the back side...

PP thoughts only, not a mechanic...

Best regards,

I will watch next time I turn it on, but I have never seen it light up so I suspect it is not connected. The 830 was originally installed on the copilot side, so a warning light makes sense. At some point it was moved to the pilot side, so perhaps the light was disabled at that point.

I have some panel work coming up, so I will try to trace the source.

Definitely not OEM and I suspect folks are right above that it is the JPI warning light, but that's not the size they ordinarily include with their unit unless its an older version.  So could be a warning light from another unit as well such as a Guardian CO or another. 

Technically every light and CB is required to labeled - so good to get this taken care of.

Nice Mooney!

I have a CB on my 2000 Ovation that isn’t labeled......I guess I should pull it and see what doesn’t work.

I had a mystery light on my panel that wasn't labelled.   After a lot of investigation it turned out to be the glideslope acquisition lamp for the autopilot.    Once I figured out what it was I checked it back when my a/p was still functional and it worked as intended.  ;)

What are the items I circled in yellow?

Those are covers to access the light bulbs for trim and flap position indicators. They unscrew but careful because they are plastic and may resist. Chances are they’ve never been removed. I removed mine once, cleaned them and applied a drop of triflow on them and put them back.

Probably was disabled. The warning LEDs on my MVP-50 drive me nuts.

That looks like a low vacuum light was installed, if you ever had a stand-by vacuum system installed that worked off of manifold pressure. If I remember correctly when I had the system installed in my 201 the warning light came with it.

I should have mentioned the things I have already eliminated in my first post. It’s not the AHARS Fail light. I have one of those and it is clearly labelled.

Turbocharged, so no standby vacuum off the manifold. It once had an electric standby vacuum pump. Separate warning light and switch still exist but I am all electric now.

A disconnected JPI caution seems like the most likely answer at this point.

Thanks for all of the suggestions.

If you are talking about the yellow/green one, the smaller one then:  it is the exact same light that I have that indicates the speed brakes are deployed.  Should be lit when speed brakes are up and off when they are down. Does the red one indicate speed brake operation in your plane?

Yes, my speedbrake light is the red one.

As I mentioned the other is like my speed brake light, it is really weak and hard to see in the day light.  I wonder if someone made an improvement by installing a better light??  Maybe look under there and see if you can see where wires go and whether the green one is wired up to something or not.
