red light,yeah,tried it and it works,been practicing walking with one eye closed when out with the dog in the evening useing a flash light,turn it off and open the that eye.
 
The red lenses do help but if the flashlight is shined directly at you from an 100 yards away (or longer) it still can be seen even under moon light depending on power of the light. Red lenses work best pointing down not horizontal to the ground and not point at anything reflective, even in WWII they still used blackout curtains even though red/filtered lights were used another note, a flashing red strobe can be seen from the air, also the Navy has used red lenses in it's signal lamps and the air port still uses red signal lights so yes red lens lights can be seen.
 
So if You were in a had to abandon vehicle because of blocked roadways or check points caught on the other side of hostile conflict trying to get home . There is vast stretches of woodland between towns if moving by night red lens shined at forrest floor and move quietly or if bugged in off trail cold camp for the night light close to ground shinning at ground if needed .
 
The red light will not throw a beam like a white light does, reflective qualities are substantially reduced, if I’m evading moving through forested area I would diffidently use a red lenses if left with no choice. Evading tactics in practically all manuals is ‘use no form of lights’ and that also means all filtered lights.

The flashlight should have about and inch and a half hood that protrudes from the lenses, on the old military angle light those can be easily extended with attachments such as the male/female coupler to extend it to 2” that’s what we used in the field.

That range you was fixing up in another post, place a red lens flashlight at the end of your range and point It to your shooting position and look, you will see what I’m talking about and then point it down 4 feet off the ground and see if you can see it, have someone with really good eye sight and adjust the lights hight until they can’t see it, old fashion filter flash light work better than LEDs or use multiple layers of the filter on the LED.

Good info . Yes Iv walked the woods many times at night with no light . I was considering areas Your not familiar with . Sink holes , bluffs , briar thickets , stumps , rotted out stumps that leave knee killing hole .
Also house clearing , room clearing with a red lens has came up in a conversation I had recently .
 
In my untested opinion, if your eyes can see the light, then others can see the light. It would depend on the angle of the light beam. Straight down would greatly limit the opposition from seeing it but not totally prevent the light from being observed. Hooded red light would be better than white light but no light, if possible, would be the best. You would have to factor in the risk of injury against the risk of discovery. Walking along an unknown, uneven surface is going to cause the light to be moving around and could accidentally be raise into an observable position. Good topic for thought.
 
Each areas around the Country have their own pit-falls, this being one of them around me.
Out here going into the forest at night can be dangerous even with a good light and even in day time and it is wise to have a good walking stick, going by red light or no light is almost idiocy.
Not only do you have to travel through unseen downed limbs you got to be worried about the lava beds that's covered with overgrown vegetation, the holes can drop 50' 100' or more into the lava tubes through a vertical shaft, if you survive the fall you would probably bleed out from the jagged wall of the shaft, cause trying to walk out of a good number of tubes ain't going to happen.

You will cross this, if you do this at night using only a red lens light and in a hurry, the photos below show the consequences, least were I am at. Hopefully the people pursuing me won't know the terrain.

I am speculating here but I figure if a red light was visible to others it would attract the eye very quickly. People are attuned from early on that RED Lights represent some form of danger and your brain will pick it out very quickly.

Apparently a red light will not light up a area like a white light will . Especially if you focus it into a beam .
 
Red light has a longer wavelength than blue light, which means that it's actually more visible under conditions like fog, dust, and smoke.

That's why car tail lights are red.

The reason has to do with a longer wavelength. If a wavelength is longer, it has a greater chance of "skipping over" a suspended particle...rather like a large wave washing over a swimmer in the ocean.

If the wavelength is smaller (like a blue light), the waves are more like small ripples in water that are blocked by the same swimmer's body.

This is also why we can't see the center of our galaxy in visible light, as the wavelength is too small and is blocked by dust...but if we use an infrared telescope in Earth's orbit (infrared is a much longer wavelength than visible light), we can see the center of the galaxy just fine because the wavelengths are longer than the average size of the intersteller dust particles.

All this means that a small blue light might be preferable to a red light on a foggy night to conceal your position, while a red light might be preferable on a clear night.

Wow! What a great place to explore! That is a young boys paradise, and a parents worst nightmare... yup, I would probably have been lost in a lava tube and never heard from again as a teenager!
