Default Lighted Switches

So while sitting with my wings complete and awaiting the arrival of the fuselage I took the time to photograph some back lighting options for AML34 Switches that fit nicely under Garmin GDU46X panels in the RV-14. These AML54 rockers from engravers.net are shown in AML34EBA4AA01 switches with LE-0504-01 LED Lights from digi-key.

These are all the same Switch and Rocker, just with different LED lights installed (really easy to change out). From left to right is Blue, White, Yellow, Green, Red. Of note, the Green is really bright and the blue is not far behind. I am doing some additional experimenting with filling the transluscent engraving with white paint to make it more readable when the light is turned off. Will post more info on that later.

Thanks again to the guys at engravers.net for sending me some sample rocker switches to play with.

As Stein would say just my 2c

Pro's:
Look "fancy"

Con's:
Cost more
Quality/reliability not as good as Honeywell toggle
Quick connect push on connectors not as robust/secure as screws
More complex to install with wiring and dimmers
Take up more room

Default Fair

Fair opinion. I would argue pros also include

Ease of switch identification in low light
Reduced risk of leaving components on when they shouldnít be (Pitot Heat, Autopilot Inhibit, etc)

Not that anyone ever leaves pitot heat turned on after landing, right. I plan to make that one yellow or red.

I do agree in some cases upper face switch dependent lights donít make sense because the normal position is ON such as the master, alternator, and avionics. In these cases it isnít really notifying you of anything that you shouldnít already be aware of based on your screens being powered.

I find the additional light indicating operation helpful for things such as pitot heat, landing light, navigation lights, autopilot inhibit, ESP-X activation, etc. just differing opinions which is why I love experimental aviation. Everyone gets to have it their way.

Default Thatís why we build

We build experimental airframes so we can choose what we want. As long as itís safe and functional, builders choice. VAF needs to limit naysayers, whatís the point to dissing others personal options?

Thanks for sharing the color options, I applaud the effort and might need.

Seems easier to criticize than create.

Default Cool Idea

I actually like the idea of illuminated switches. Thanks for sharing, I will look into them.

Default Colors for IFR

So for the experts on IFR lighting, what colors are best for an IFR panel? I was taught green or yellow, but my IFR ground school said to use white when on final and dont worry about preserving night vision because proper color rendering was more important.

What are everyone’s thoughts on color for IFR?

Default Data point

At work, pretty everything is white light with the exception of a red lense on the grimes light...that never gets used...

I hadnít really thought about lighting in regards to IFR as much as night. During daylight any of the colors would be fine and during daytime IFR I suspect the same would hold true.

Now at night, if using these type of switches I would definitely have them on a dimmer. Especially if you want green, blue, or white. While preserving night vision may not be critical, you still donít need a bright set of lights shining in your eyes. Yellow was definitely the most docile of the colors and if all else fails I think that would be my fallback color. Good this is the LED lights that change out so easily are about $1 each. So easy to change the color if you change your mind.
