Light bite usually means one of two things, first and foremost its a smaller species of fish like small yellow/white bass/small bass, or even small crappie. When I run into this, I like to make sure they really have the rod buried before i set the hook and give what ever is biting more time to eat the bait. I will only stick to an area with this kind of bite if I am catching a good fish now and then to go along with all the light bitters or I move on. The other thing to consider when getting light bites is size of your bait, try downsizing if you think the light bitters are crappie, but most times it is the aforementioned. Not being so fast to yank or down sizing is how I like to combat light biting fish.
