When I lived in Georgia I fished at night with lights for crappie. Some of the best places to set up are areas with some structure. I have found under bridges to be about the best, although it does work in open water at times where you have transition areas.The idea behind the lights is to attract the baitfish, which in turn attracts the predator fish, i.e. crappie. If you know of an area where the crappie are during the day you should be able to find them close to the same area at night. When I say close to the same area what I mean is that they will probably move into shallower water at night, hence my previous statement of setting up in transition areas. If you set up and don't attract any baitfish after a reasonable period of time it may require you to move to a different spot, but figuring that out can be tricky. I have sat in a spot for a couple hours and have nothing around, then suddenly the baitfish move in and the crappie close behind. That is when the fun starts. Hope this is of some help to you.
