The Sea Sense Round Light Base w/Lock Collar is a universal stern light mounting solution designed for boat owners who need reliable, weatherproof installation of navigational lighting. Whether you're setting up a new light fixture or replacing worn hardware, this round base accepts most standard navigational lights on the market, making it a practical choice for retrofit work or new builds without the need to source model-specific mounts.
The included rubber cap provides essential weather protection when the light isn't in use—a simple but effective detail that keeps saltwater, rain, and debris out of the electrical connections and base cavity. Proper sealing is critical on the water, where corrosion can degrade fixtures and create safety hazards, and this cap works alongside the base's design to extend the life of your lighting system.
The Sure-Fit locking collar secures your light fixture firmly to the base, preventing vibration-induced loosening during rough water or travel. This is especially important for navigational lights, which must remain reliable and properly aimed in all conditions. The collar tightens down smoothly without requiring special tools, making installation and maintenance straightforward for most boat owners and marine technicians.
The Sea Sense round light base accepts almost all navigational lights on the market today. If you're uncertain about your specific fixture, check the light's manual or base diameter—the universal design covers the vast majority of common stern light models.
You receive the round light base, a rubber cap for weather protection, and the Sure-Fit locking collar for secure installation.
When the navigational light is not in use, the rubber cap seals the top of the base to keep water, salt spray, and debris out of the electrical connections and interior cavity. This helps prevent corrosion and electrical issues, which are common problems in marine environments.
Yes. The Sure-Fit collar tightens down without special tools and holds the light fixture firmly in place, preventing loosening from vibration or rough water conditions.
