Trep-
I normally only night fish on lakes that I'm pretty familiar with...
That helps with knowing where weed beds, shore structure, docks, etc. are located.
Since I pretty much only throw topwater at night, I focus on shallower flats, docks, and weedbeds...
I don't usually use any lights, other than a small flashlight for knot tying, when I'm fishing. I do keep a big halogen spot light at the ready for moving from spot to spot...
