If you think there is a chance that you will use your boat outside of daylight hours (dawn till dusk) it would be a wise move, and a legal one, to have all your required lights in place and working. This Emergency Navigation Light 3PCE Kit is the easiest and safest way you could add navigation lights to your boat if your permanent ones should happen to fail for any reason. With a Port, Starboard and an all-round white light included, it has all your required lighting in the one pack. Operating on 3 D Cell batteries and with rubber O-ring seals, this is a very handy safety item to keep on board your boat. For the full range of lights, globes, LEDs and even battery-powered lighting available at BCF, call into our store and talk to one of our friendly, knowledgeable staff to find the one that's right for you.
