Let your crew sleep while you navigate at night, with the help of this tiny, beautifully made nav station light. Dimmer control infinitely adjusts level from off to full bright. Focus from spot to flood. Flip from red to white. Fully adjustable in all directions. Push button release for hand-held use -- and its five-foot coiled cord makes it great for that purpose. This unit is 12-volt. Made of die-cast aluminum alloy, it measures just 31/2" long x 13/4" in diameter.
