Attwood Rectangle 2-Pin Base for 12-Degree Angled Light Pole

The Attwood 911339-7 base provides a neat, finished look when the light is stowed, thanks to a swivel cover that closes over the socket. This base uses a bright zamak finish for corrosion resistance and a classic appearance. Best for boats that prioritize a clean, professional look and straightforward 2-pin connections.
Best for: medium to larger vessels with angled light poles where aesthetics and a secure socket are priorities. The swivel cover helps protect the socket from spray and debris. A potential limitation is its specific 12-degree angled design, which may not suit all pole configurations.
Shoreline Marine Stern Light Base 2-Prong Zamak

This base features triple chrome plated Zamak and a spin top cover, fitting most 2-pin style pole lights. It’s well-suited for boaters who want a traditional, durable metal base with a secure, rot-resistant connection. The design favors reliability in saltwater environments and straightforward installation.
Best for: owners needing a classic, durable 2-pin base with robust corrosion resistance. Better for: boats that rely on a conventional look and easy field maintenance. Caution: ensure the pole’s lighting style matches a 2-pin base for a proper fit.
attwood 910R2PB-7 Marine LightArmor 910R 2-Pin Round Plug-in Base

Constructed from durable black composite, this base supports 2-pin plug-ins compatible with Attwood locking-collar pole lights. It emphasizes a secure, rattle-free connection with nickel-plated contacts to resist corrosion. This base is ideal for boats exposed to harsher marine conditions where long-term electrical reliability matters.
Best for: boats requiring a moisture-resistant base with a locking-collar compatible light system. Choose this if you want reduced movement and corrosion resistance. Limitation: designed for compatible Attwood light systems; verify compatibility with your light model and mounting scheme.
Better Boat Boat Stern Light Base, 2-Pin Plug

Better Boat’s base offers easy installation with red and black leads exiting the base, ready to connect to existing wiring. It uses weatherproof construction with a hinged cap to seal the 2-pin socket when no pole is installed. It accepts standard 3/4″ diameter 2-pin stern light poles, with vertical and angled hole options.
Best for: DIY installers seeking straightforward wiring and a weatherproof seal. Better for: smaller to mid-sized vessels that prioritize user-friendly installation. Caution: verify exact hole size compatibility with your boat’s deck to avoid loose mounting.
EBQOSK Stainless Steel Boat Stern Light Base

EBQOSK offers a universal plug-in base with a 0.75″ diameter compatibility for 2-pin navigation and all-round stern lights. Made from saltwater-resistant stainless steel, it’s designed for longer lifespans in challenging marine environments. This base is a solid choice when you need broad compatibility and corrosion resistance.
Best for: boats that require a universal, corrosion-resistant base that works with many 2-pin poles. Better for: sailors who frequently use stern and navigation lights in saltwater. Limitation: ensure your pole’s connector diameter matches the 0.75″ specification for a secure fit.
Buying Guide: How to Choose the Right Boat Anchor Light Base
- Pole compatibility: Most bases use a 2-pin plug; confirm the diameter (commonly 3/4″ or 1/2″) and whether you need a locking-collar or standard plug.
- Material and finish: Stainless steel excels in saltwater; zamak provides a bright, chrome-like finish; high-quality composites reduce corrosion risk in harsh conditions.
- Installation style: Some bases require simple drilled holes, while others feature pre-wired or plug-in designs. Consider your skill level and onboard wiring setup.
- Protection: Look for hinged caps or swivel covers to seal out rain, debris, and spray when a light is not installed.
- Boat type and size: Larger vessels often benefit from more robust bases with locking collars, while small boats can use lighter, plastic or composite bases.
- Mounting and hole size: Check the required deck hole size (for vertical, angled, or straight bases) to ensure a snug fit.
- Maintenance: Choose bases with corrosion-resistant construction and contacts that resist oxidation to maximize longevity.
- Placement: Consider ease of access for installation, serviceability, and ensuring the base doesn’t interfere with other deck hardware.
FAQ
- Q: Will any 2-pin base fit any 2-pin light? A: Most 2-pin bases fit standard 2-pin lights, but confirm the pole diameter and locking mechanism to ensure compatibility.
- Q: Are stainless bases better for saltwater than zamak? A: Yes, stainless steel generally offers superior corrosion resistance in saltwater, but quality and coating matter for both materials.
- Q: Do all bases support vertical and angled poles? A: Not all; some are designed for specific mounting angles. Check the hole size and design before purchasing.
- Q: What maintenance is needed for anchor light bases? A: Inspect electrical contacts for corrosion, ensure the cap seals well, and verify mounting screws remain tight.
- Q: Is a locking-collar base worth it? A: For boats in rough seas or with frequent movement, locking collars reduce wobble and improve connector stability.
- Q: Can I install these bases myself? A: Most bases are designed for DIY installation, but follow the product’s wiring and mounting instructions for safe operation.
