Been trying to find that on mine. Thanks for the photo!

Most people don’t know that is hiding under the instrument panel...

One part, many people don’t fly at night....

The other part... the bulb went dead decades ago...

The third part... it doesn’t get mentioned in the owners manual anywhere...

If there is a fourth part... the twist iris got twisted shut before the change in ownership...

It is a twist iris, and push to test, like the gear lights...

My manual actually refers to it, I just forget to find it when I crawl under there for other things. 
Need a reason to wedge my head and shoulders down there to get the right viewing angle.(Insert upside down smiling emoji)

Next time you are adding post or panel lights... the lights are all wired to a source in the same area...

Makes sense! Thanks guys!

Cool, as many times as I've been laying on my back on the floor board, ankles over seat back, I've never seen it.  Think I'll go slide in there and look now.

Does anyone actually look at the fuel selector??

I reach down and turn it through the "off" detent to the right/left detent as desired.  I want to "feel" it drop into the detent; no point in looking.

I can't crawl under the panel anymore!   :-)

Don't bend that good any more

Mine was too dim, so I replaced it with a different Whelen light fixture with a LED bayonet bulb.  Now I can see the fuel selector much better at night.
