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

Best for boats that require a compact, stylish base with a finished look when the light is stowed. The base uses a swivel cover to conceal the socket and features a bright zamak finish for corrosion resistance. Suitable for small to mid-size vessels that favor a clean deck profile. Limitation: the 4 by 1 5/8 inch footprint may not fit very tight compartments or unusual railing designs.
Shoreline Marine Stern Light Base 2-Prong Zamak

Best for budget-conscious boaters who still want a chrome-plated finish. This base features triple chrome-plated zamak and a spin-top cover for weather sealing. It fits most 2-pin style pole lights. Choose this if you need a straightforward replacement that’s easy to source; avoid if you require locking collar compatibility or heavy-duty silicone seals.
Attwood Oval 2-Pin Base for Angled Pole Light

Best for angled pole lights with a locking collar and a 1-3/8″ installation hole. The oval design supports angled mounting, providing a secure, watertight seal. The base is black, blending with many hull colors. Limitation: installation requires a precise hole and may not suit straight, vertical lighting setups without modification.
Young Marine 2-Pin Straight Base

Best for straight-base installations on boats with unplugged, dry-cap protection. It fits standard 2-pin and 3/4″ diameter light poles and includes a cap to keep moisture out when not in use. Choose this if you prioritize a simple plug-in setup and dry storage; limitation: may not fit heavy-duty locking-collar poles.
Attwood 910R2PB-7 Round Plug-in Base

Best for moisture resistance and a secure connection with locking collars. The base uses a durable black composite housing, nickel-plated contacts for reliability, and compatibility with Attwood All-Around pole lights. Better for boats where a rattle-free, stable electrical connection is a priority; caution: compatibility is strongest with Attwood brand locking collars.
Better Boat Stern Light Base with 2-Pin Socket

Best for easy installation and weatherproof protection. The base accepts standard 2-pin poles and offers a hinged protective cap to seal the socket when not in use. It supports vertical and angled setups with compatible hole sizes. Limitation: bulkier design may not suit tight spaces on small V-hulled boats.
EBQOSK Stainless Steel 2-Pin Base

Best for corrosion resistance with saltwater exposure. The base is pre-wired for quick installation and uses saltwater-resistant stainless screws. It securely holds 2-pin navigation and anchor light poles with a 3/4″ diameter. Choose this if you need a universal, durable installation; limitation: the stainless construction can be heavier and pricier than plastic alternatives.
Seachoice All-Round White Light Spare Base

Best as a spare base for all-round white lights. The zamak die-cast with Perma-Plate chrome finish ensures a durable, corrosion-resistant option with a swiveling cover to seal out weather. Ideal as a replacement or backup base; limitation: primarily a spare, not a primary heavy-use base for high-demand lighting systems.
Buying Guide — Key Considerations
What hole size is required? Most 2-pin bases use a 1-1/4″ to 1-5/16″ installation hole; verify your boat’s hole dimensions before purchase.
Material matters. Zamak die-cast or chrome-plated zamak offers great corrosion resistance; black composite bases provide moisture resistance and lighter weight.
Locking collars and fit. Some bases are designed to work with locking collars; check compatibility if you plan to use Attwood All-Around lighting.
Cover design and sealing. Hinged caps and swivel covers help seal out rain and debris; consider interiors with frequent exposure to spray or spray-laden weather.
Installation practicality. Some bases are pre-wired or pre-screwed for easier installation; others require direct wiring or crimp connections. Choose based on your wiring confidence and tools available.
