Many boat owners though are finding that as well as producing an interesting and unusual appearance, underwater hull lights also do an admirable job of also providing practical benefits. One of the most popular uses for underwater lighting is fishing, with hull lights acting as excellent bait fish attractors, which in turn attracts a whole host of larger and more desirable game fish species. Using underwater lights for fishing has gotten so popular in fact that a whole slew of companies have sprouted up which specialize in providing a dizzying array of lights geared only towards the sport fishing enthusiast. There is no doubt that using light to attract fish can be effective, and many anglers have used the trick of setting bright lights over the waters' surface to attract fish for decades. Modern versions of this method though, make the process as simple as flipping an onboard switch and illuminating the entire area around the boat; a far cry from the old days where a gas lantern hung from a pole or rope was standard practice.
