Do not understand the Blue lights inside windshield?

Red light allows your eyes to adjust to the darkness faster than any other color.

 

Red light doesn't destroy your night vision like white light, unless it is really bright. That's what you see in submarine/airplane war movies.

 

I thought the military used Green lights on the interior for night operations?
Every old freightliner was made with Green dimmable dash lights, and Green floor lights? I do believe there was a reason for this.
Maybe less stress on the eyes?

 

I just found this on google.

Interesting article if your interested in that kind of information.

Navigating the Dark: How to Preserve Your Night Vision

 

I have never ever seen a factory FL with green lights.

I've been working with my wife's doctors and they seem to think that red is better, it seems with the fact that the military and other organizations also use red in dark rooms seem to have something to do with this.

Green that comes from night vision (Image intensifiers) is produced by the camera tube so they use green lighting to keep it consistent for the eyes.

 

Personally I can not stand anything other than green interior light in the wee hours. Red, blue both tick me off.
The common red light light gauges now perturb me very much also.

My 2005 Columbia had green foot well lights. Not sure if factory but they did match the gauges.

 

Back in the old days,early 70's,when CB's first became popular in trucks,there was an informal trucking radio group called Oscar Myer Weeners,or some thing like that. They had a light in the center of there dash,and if you were a member,and saw another driver going the other way at night,with his light on,they would go to their linear powered secret sideband channel,and talk for hundreds of miles. We just didn't have much to do back then. They just faded out after a while. True story,and no,I wasn't a weener.

 

These lights?
Blue is bright as heck. Hard to see the road lol

 

Trying to see better by choosing another color other than white for in-cab lighting is not very productive for a driver operating on the road. Even though certain in-cab colors might help preserve night vision if not too bright under ideal darkened-environment conditions, driving isn't one of them. Night-adapted eyes lose that feature as soon as the headlights of another vehicle hit them, such as seeing them through the windshield or in the mirror. This is especially true when those vehicle lights are blue-tinted and extra-bright LEDs or HIDs that are throwing walls of light all over the place.
