Buying Guide
What should you consider when choosing a 3-pin navigation light base?
- Compatibility: Confirm the base matches your light’s brand or that the mounting pattern is universal for 3-pin systems.
- Material and finish: Aluminum or chrome-plated bases resist corrosion; black or gray flanges reduce glare and match boat aesthetics.
- Design features: Look for threaded locking collars for a secure fit or damping designs to minimize rattling.
- Mounting method: Check the number and size of mounting holes, and whether screws are included or require a separate purchase.
- Environmental conditions: For saltwater use, prioritize bases with corrosion resistance and weatherproof covers.
