RE: diagram of a deer's eye
....hate to tell ya this..but I have several red LED flashing lights thatI can wear into my stand....they cost about 5 bucks at Wal-mart. Press the button to turn them on....press it again to turn it off....pretty simple.If you want something a little more fancy,the VIP light will run you about 50-75.00 dollars I think.(can't remember what I paid for mine...been several years now)
