Mystery light in pilot footwell

[podair]

what is this light for, if this is a light? 

M20F pilot footwell, looks like it is part of the airspeed switch (landing gear safety device, ie don't retract under a certain speed).

I believe it’s intended to simply illuminate to assist in viewing the fuel selector switch setting (on the floor under the pilot’s feet).

There is no lettering on the wire so it is not stock Mooney.

It is.  It’s to illuminate the fuel selector.

I don’t remember anything in the POH detailing the fuel selector light...

My M20C had one. I came across it while working on getting panel lights to dim properly... all the panel lights are grounded to a bolt near the fuel selector light.

Looks similar to the gear lights on the panel in construction... does it have an iris twist control for dimming?

Best regards,

Yes it does have an iris

My POH identifies it.

Mine has one also....   was wondering....  now Im  not...   Thx..

Mine is really dim even with the iris fully open.

If the 28 volt bulb is put in instead of the 14 volt it will be dim.  Found wrong bulb in my mag compass when I first got it.  Don’t know if that’s your problem.

Yup, that's what it is. See @ragedracer1977 post with the POH excerpt.

My 65 E has it.

Hey, look! My '70 C does too! Now I need to stand on my head and look for it . . . .

Yeah, those of us with later-model F's just have to Fumble around in the dark.

It's OK I got red panel lights and no one else did, so I am good.

Actual panel lights or those hot bullets on the overhead?

If memory serves me well, panel lights were options. These are part of plastic overlays and controlled by rheostat overhead. My '67F has them...

Ha...  I found a power source from a socket I had no idea what it was for...  Now it powers a 2K watt heater..  LOL
