Attwood 5110-30-7 30-Inch All-Round Frosted Globe Navigation Light, USCG Certified, Fits Boats up to 39.4 Feet

The Attwood 5110-30-7 is a traditional-style all-round frosted globe navigation light built as a legacy replacement pole light for boats up to 39.4 feet (12 meters). It delivers a full 360 degrees of illumination and is USCG certified for 2-nautical-mile visibility, keeping a vessel legally compliant and clearly visible to other boaters after dark.

The light stands on a 30-inch aluminum pole finished in aluminum-silver, topped with a clear, frosted acrylic globe lens that diffuses the beam evenly around the horizon. It uses a 2-pin locking-collar base configuration, so it drops directly into standard 910R2, 910V2, and 910T2 light bases. With the locking collar removed, it also adapts to 2520, 911339, and 911370 bases, giving it broad compatibility across common attwood base styles already installed on a boat.

Attwood ships the 5110-30-7 ready to install, including a 9-watt wedge-base incandescent lamp so it can be mounted and put back into service without a separate trip for a bulb. It runs on a standard 12-volt marine electrical system and is intended as a direct, no-assembly-required replacement for a worn or broken stern or all-round light pole.
