LED lights consume up to one-10th the power of incandescent bulbs and are not susceptible to vibration like incandescent bulb elements are. When mounted in waterproof fixtures like a bow light, the double-ended festoon bulb is bright and durable and barely draws amperage, making it ideal for at-anchor use. The spade-ended bulb replaces trailer stoplights and gives the same advantages on wheels as the festoon does. From $19.95; sailorsams.com
