Better Boat 2-Pin Stern Light Base Socket — Vertical 3/4" Pole, UV & Salt-Resistant with Hinged Cap

This Better Boat 2-pin stern light base is a weatherproof, quick-swap socket that accepts standard 3/4" 2-pin navigation and anchor light poles for secure, vibration-free connections.

Whether replacing a worn mount or upgrading your boat’s light fittings, this plug-in base offers a simple, durable solution. Available in vertical, angled (12°), and stainless-trim styles, the base is built from UV- and salt-resistant plastic, includes a hinged protective cap, and connects easily to existing wiring with pre-attached red and black leads.

How easy is it to install this light base?

Installation is straightforward and made to minimize time below deck. Red and black leads exit the base ready to tie into your boat’s wiring; no internal terminal work is required. The unit drops into a drilled hole and secures with the included stainless steel screws for a tidy finish.

• Pre-attached red and black leads for quick wire nut or crimp connections
• Fits standard hole sizes: vertical (1-1/4"), angled (1-5/16")
• Comes with stainless screws for corrosion resistance

Will this base fit my navigation, stern, or anchor light pole?

Compatibility depends on the pole’s pin pattern and diameter. This product is a 2-pin vertical-slot socket sized for poles that use that exact vertical slot pin configuration. It accepts standard 3/4" diameter poles secured by a tightening screw.

• Designed for 2-pin vertical-slot light poles only
• Accepts 3/4" diameter poles with a tightening screw for secure hold
• Choose vertical, angled, or stainless trim to match pole orientation and deck hole size

How does the socket hold up in marine environments?

The base is molded from heavy-duty plastic formulated to resist UV damage and saltwater exposure, and it includes a hinged protective cap to keep rain and debris out when no pole is installed. The combination of materials and design keeps the electrical connection cleaner and reduces maintenance needs.

• UV- and saltwater-resistant plastic construction
• Hinged cap seals the 2-pin opening when unused
• Stainless steel screws help prevent corrosion at the mounting points

How quickly can I swap or remove a light pole?

Swapping poles is fast and tool-free in most cases: loosen the tightening screw, lift out the pole, and reinstall another compatible pole. The tightening screw holds poles firmly in place while underway to prevent vibration or loosening.

• Tightening screw locks pole for vibration-free use
• Loosen to remove or replace pole without complex disassembly
• Capable of repeated swaps for seasonal or temporary lights

Who is this for? Boaters who need a reliable, simple mounting solution for 2-pin stern, navigation, or anchor lights will benefit from this Better Boat base. It's ideal for owners replacing old sockets, fitting a new light pole, or standardizing light mounts across a small fleet. Choose the vertical, angled, or stainless-trim style to match your deck hole size and desired pole orientation.
