Well, i have not night fish much for the pass few years. But when i did do it alot i ended up doing away with the green lights and started using the floating head lights. To me the green light was way to bright and caught way more under the floating lights. But 99.9% of my night fishing was on main lake. Couple years ago i started going in the back of creeks. What i seen is the crappie would bite right around night and have an hour in the middle of the night and right before day light on most nights. Sometimes it is on as soon as you start and other times real late. A lot people dont agree with me on this but i believe in it. Depends on the moon phase it they bite early, late or all night....but i fished all night every time i went reguardless what....
