Buying Guide
What base type fits my light pole? Most bases support standard 2-pin stern light poles or 3/4″ diameter poles. Check the exact hole size (1-1/4″ vs 1-5/16″) and the pole diameter before purchasing.
Which finish and material matter? Stainless steel resists saltwater better, zamak die-cast offers a bright, durable finish, and composites can be lighter and color-matched to your hardware. Choose based on exposure, maintenance preferences, and aesthetic goals.
Is installation tool-free possible? Some models include pre-wired leads and simple screw-in or snap-in mounting. If wiring is needed, confirm you have the necessary insulation, connectors, and basic wiring skills.
Do I need a weatherproof design? If your boat frequently encounters rain, spray, or high humidity, opt for bases with hinged caps or sealed sockets to protect electrical contacts.
Are there compatibility caveats? Review the unit’s compatibility with your light poles (2-pin vs. locking collars vs. threaded bases) and ensure the base can accommodate your preferred navigation light model.
