SEACHOICE Fold-Down Masthead & All-Round White Navigation Light for Boats Under 66 ft — 3-Mile Visibility, 12V with Mounting Adapter

The SEACHOICE fold-down masthead and all‑round white light is a compact, foldable navigation lamp that gives up to 3‑mile visibility for sail and powerboats under 66 feet.

This compact marine lamp pairs durable construction with straightforward installation so your vessel stays visible after dusk or in low visibility. The lamp folds down when not in use or when stowing a boat cover, mounts vertically on a standard 3/4-inch anodized aluminum tube, and includes two 12V DC/8 CP bulbs and mounting adapters so you can set it flat or in a "V" position.

How bright is this light and what range can I expect?

The SEACHOICE lamp uses two included 12V DC/8 CP bulbs and clear lenses to create a bright, all‑round white output rated for roughly three miles of visibility in typical conditions. Performance depends on weather and sea state, but it meets common visibility expectations for vessels under 66 feet.

• All‑round white beam designed for 3‑mile visibility
• Comes with two 12V DC/8 CP lamps for immediate use
• Clear lenses maximize light transmission

How easy is installation and what mounting options are available?

The lamp has a pre‑drilled chrome‑plated zinc base that accepts a pair of #8 screws, so basic hand tools are all that’s required for mounting. Two plastic adapters are supplied to let you install the unit flat or in a V position for different mounting surfaces and mounting angles.

• Pre‑drilled chrome‑plated zinc base ready for #8 screws
• Includes plastic adapters for flat or V mounting configurations
• Designed to mount vertically on a 3/4‑inch anodized aluminum tube

Can this lamp be folded down and how durable is it?

Yes — the fixture folds down to prevent damage while the boat is covered or during daytime storage, reducing snagging and wind resistance. Materials are selected for marine use: an anodized aluminum tube resists corrosion, and the chrome‑plated zinc base and clear lens provide reliable service in coastal environments.

• Fold‑down design for protection and compact stowage
• Anodized 3/4" aluminum tube for corrosion resistance
• Chrome‑plated zinc base and rugged clear lens construction

What are the physical dimensions and compatibility details?

The light stands 10‑1/4 inches tall with a base footprint of about 2‑7/32 inches long by 5/8 inch wide, matching common masthead mount points on recreational craft. It’s intended for sailboats and powerboats under 66 feet and is compatible with standard 12V DC systems.

• Overall height: 10-1/4 inches
• Base size: 2-7/32" L x 5/8" W
• Designed for 12V DC electrical systems on boats under 66 feet

Who is this for: Boaters seeking an affordable, low‑profile masthead/all‑round white light that installs quickly and folds down for protection will appreciate this SEACHOICE unit. It’s ideal for weekend sailors, small cruiser owners, and anyone replacing OEM masthead lamps who needs straightforward mounting options, solid materials for saltwater use, and immediate functionality with included bulbs.
