I've seen blue,red,green,amber and clear lenses on the flashlights but I don't know why you would use the other ones
The red is used to cut down the light at night so you are not a target and it helps your night vision. The other colors are just gimmicks and have no value other than the color if you like it.
Actually, the red and blue both preserve night vision and the blue is less visible to night vision devices that work nearer to infra red. Also, it can help to ID friendlies...
All I know, is that if you put the word "Tactical" on the package, it will cost about 5 times as much.
A Thomas Brothers map is virtually impossible to read with a red light.
Do you often read T. Bros. maps in tactical situations during road trips? lol. "Honey... I mean Alpha Delta... hand me the map. And the flashlight. NO! Not the normal flashlight! The Wilson's will see us. I need the RED flashlight."
Yes, cockpit lighting for night is red and flashlight lens covers are red for night vision. Just be careful using colored pencils/pens to annotate your maps/air charts because the red light will change the apparent colors! Red lines sort of disappear, if I recall correctly, and green becomes black. Could become a problem!
