attwood 12° Angled 2-Pin Rectangle Marine Light Base One Size — ZAMAK construction, tinned copper leads

The Attwood 12° Angled 2-Pin Rectangle Marine Light Base is a corrosion-resistant ZAMAK replacement socket designed for 12° angled pole lights, providing a keyed two-pin connection, sealed swivel cover, and 7-1/2" tinned copper leads for reliable 12V DC operation.

This heavy-duty light base is built for the saltwater environment and engineered to accept Attwood Frosted Globe (5110), Anti-Glare (5300), and Bi-Color (5091) pole lights. It combines rugged metal construction with corrosion-mitigating contacts and wiring so your navigation or courtesy light stays secure and electrically sound. The compact rectangular form fits standard openings and mounts flush for a tidy installation on decks, rails, and light poles angled at 12 degrees.

How does this base resist corrosion and long-term wear?

The body uses ZAMAK alloy for structural strength while nickel-plated, multi-crimped contacts minimize galvanic corrosion. Tinned copper leads and a sealed swivel cover further reduce exposure to salt and moisture, extending service life in marine settings.

• ZAMAK alloy housing resists cracking and deformation
• Nickel-plated contacts reduce corrosion at electrical points
• 7-1/2" tinned copper leads prevent wire corrosion
• Swivel cover seals the socket when the light is stowed

Will it fit my existing pole light and mounting hole?

This base is dimensioned to accommodate standard pole light fittings: the rectangular flange measures approximately 4" x 1-5/8" and the socket installs into a 1-3/8" diameter hole. Three countersunk screw holes allow a flush, secure attachment without special adapters.

• Compatible with 5110, 5300, and 5091 Attwood series
• Fits 1-3/8" diameter installation hole
• Rectangular flange ~4" x 1-5/8" for neat mounting
• Three countersunk holes for stable, flush fastening

How does the keyed two-pin socket improve safety and usability?

The socket is precision-keyed so the light plugs in only one correct orientation, preventing reversed connections and reducing the chance of shorts or intermittent contact. This makes swapping lamps quick and foolproof for routine maintenance or replacement at sea.

• Precision-keying prevents incorrect insertion
• Reduces risk of electrical shorts and loose contacts
• Simplifies lamp installation and replacement
• Works seamlessly with Attwood two-pin pole lights

What electrical and practical features should I expect during installation?

The base includes 7-1/2" of tinned copper hardwire leads ready for 12V DC wiring and a layout compatible with most marine light circuits. Its design keeps the wiring organized and the mounting low-profile for a professional finish on decks or rails.

• 7-1/2" tinned leads for corrosion-resistant hookups
• Designed for 12V DC marine systems
• Low-profile rectangular flange for discreet mounting
• Integrated swivel cover protects the socket background

Who is this for: This Attwood base is ideal for boat owners, marine technicians, and fleet maintainers replacing or upgrading angled pole lights on recreational boats, work vessels, or any craft frequently exposed to saltwater. Choose it when you need a durable, keyed, and easy-to-install socket that matches Attwood 5110, 5300, or 5091 series lamps and delivers dependable 12V connections in harsh marine conditions.
