Alright so my wife is headed off for vacation for a couple weeks and I want to give this night fishing a shot, it will be at Jordan or Shearon I am not sure yet. My question to you guys is.

-What lights do you recommend, I will be buying green but I am not sure which brand.
-How many lights should I use, I would like to buy two but if I go with a good quality light it will more than likely only be one.
-should I buy a new deep cycle battery just for the lights or can I use the one my fish finders run off of (I have one for the trolling motor and another for the other electronics).

Another question, should I focus more on bluegills in the middle of the summer or is the crappie fishing a year round thing down here in North Carolina. I would like to stick with crappie but bluegills are just as good in my book.

Thank you and I appreciate any and all help.
