Getting ready to order an LED plug in type anchor light, and have been debating on what length to get. While night fishing I envision someone sitting on a pin mounted seat on the rear bench that has a deck going all the way back to the transom. So I want to make sure I get something tall enough to keep the glare out of whoever is back there eyes. Mostly it will be used in the early morning hours while running to a duck/goose hunting hole, so I don't want anything obnoxisouly long. Should I be looking for a certain length? Or maybe there is something out there that is anti-glare?
