Hi Tony,
I do a LOT of hunting for nutria, possum, and raccoons at night. Have probably taken over 500 in the past 15 years. Small game hunting is just about my favorite activity. From Nov. 15th to March 15th is when our season is open. It is an absolute blast. You can get a good light for this at Wal-Mart, etc. It's a Black and Decker light that takes 4 C cell batteries. Works great and will allow for shots up to 30+ yards if you want to take them. The light has two settings, high beam will last 20 hours and low beam will last 72 or something like that.
The lights that charge up have a lot more power, but die out in less than an hour.
It was the need for a good small game head for shooting nutria at night that actually motivated me to design the Talon small game head that eventually spawned Red Feather Archery.
I've used that head to take dozens of nutria, and dozens of raccoons and opposums. It's great for nutria out of my trad bows, but I would NOT use it for raccoons! They are thick skinned and tough. For traditional shooters broadheads are the way to go with raccoons.
Couldn't tell you on the foxes, haven't ever shot one. If it's legal in your state definitely give it a shot!
