Green lights work best because the green light carries farther in the water than any other light in the spectrum. Good for drawing in more bait. If you want to use a white light then make sure you can submerge it if you don't want bugs gathering around the light. I use green LED light strips around the outside edge of my boat and it works fine for drawing in the plankton and bait fish but when I put an LED spotlight on the water it really draws in the bait. Experiment and see what you need.
