Default RGBW

It is a definite overkill, but I have RGBW LED strip in my aircraft. Each color is driven by a separate pot allowing red, green, blue and white to be selected and dimmed individually giving any color or combination of colors. All of my switch labels are backlit, under IP lighting, floor lighting and overhead use various lengths of LED strips controlled by a master color selector.

You can get any single color or RGBW combination 16 foot strip 12V from Ebay for under $10. They can be cut every 2 inches and connected directly to the 12V power source. For dimming use a 1K ohm pot on the (a switched pot eliminates the need for a separate switch) power supply or ground lead for diming. That will give you very dim to full bright output and no radio interference.

I went with dual (white and blue) LED strip (from ACS 5 yrs ago) in my plastic plane. I was going with white, but an airport know it all told me it should be blue. So, a rare violation of my KISS.

A toggle selects blue, white, or both. A separate pot controls brightness on the strip and three other lighting groups. I'd do it again- kind of cool.

This is what I did. Simple inexpensive 12V LED string from ebay, run through a 10K pot with a large enough current rating. Be sure to buy the LED strings with the lower power LEDS. The more powerful ones are too strong to get the lumens low enough, even with a dimmer. I think they are the 3xxx series, not the 5xxx series LEDs.

The military concluded that ~500 nm light (a green with with hint of blue) is the best for contrast in low light conditions and for things like reading a map. However, long term low light exposure is generally better with red, although for those of us that are color challenged" and have to get a special test just to keep our licenses (at least until BasicMed came around...thanks), low level white or light green is just fine. The goal is to not flood your retina with light.

YMMV.
