I rarely, if ever use lights of any kind. I always try to get there early if I have to walk through timber. Turkeys may not fly away from the roost, even if you walk right underneath them, but come sunup they will gobble then pitch the other way. (I know there's always exceptions) If you stumble through the dark woods you may alert them, but they hear cows, possums, coyotes, raccoons, etc making a lot of noise when they traipse through the timber so they are not that scared by it. None of those critters have lights of any color. Even if I make them a little uneasy, I am set up so early they forget about those weird noises come sunup.
You may be able to do it and get away with it, but I would rather not risk spooking the only birds in the area.
