RE: Head Light??
Reflexkid
If you wear a hat with a bill on it you might want to check out the Stylus by Streamlight. I am using one this year and have tested it and it works pretty well. It clips on the bill of your cap and works similar to a headlamp. I picked up the green LED light and according to the literature deer can't see that color light........not real sure that is correct, but that is what they say.
Good Luck
