None...I have never used a flashlight going to my treestands in the morning. Why risk spooking deer? If you' re walking through the woods they may be curious, or perhaps uneasy but could easily dismiss it as something natural but if they see the light you' re done IMO. I' ve walked to within arm' s length of deer in the dark that I don' t think I would have seen if I would have been using a flashlight.
