All,



I've just added a lip around the instrument panel with the intent to  

shield those little LED strip-lites-on-a-tape in lieu of lighting  

individual instruments; these little puppies are available in red and  

blue...and supposedly, the blue ones are getting all the buzz, though  

I'm not sure why.



I'd assumed I'd use the red ones for maintaining night vision, but am  

now wondering how red cockpit lighting affects EFIS and GPS  

screens...thinking perhaps that the red light may compromise the their  

legibility.



Has anyone fitted these LEDs along w/ EFIS and GPS and tested the set  

up, either on the bench or in flight?

Hi Fred,



I've been flying with red strip LEDs for about a year and have seen

no problems with my Blue Mountain EFIS.  Consider also putting a strip

along your fuel sight tube, it really helps see the level.

Hi Fred,



I am not speaking from experience, however the EFIS and GPS are light

generators, and don't depend on white reflected light in order to see their

colors properly. They generate their own. My guess is the cockpit lighting

will not affect the EFIS and GPS screens in any way.....there could be a

physiological affect on the eyes, if the red cockpit lighting sensitizes the

eyes to colors differently....but I would think it would be negligible.



My $0.01,

Greg
