New for 2007! Add lights to the 4-Speaker Bar and you have the 4-Speaker Bar with Lights! Now, other boats will not only hear you, but see you as well! With 3 bow facing lights and an underside LED on each speaker, you'll find your way safely home in the dark. The 50 Watt bulbs are fully enclosed to prevent moisture fogging the inside of the lights. Universal clamps fit tower sizes from 1-5/8" to 2 ½".
