Everyone here is a current or past cruiser — we’ve docked short-handed, re-rigged at anchor, and chased 12V gremlins too. Not sure this is the right fit for your boat? Send us your question before you order and we’ll give you a straight answer.
Check fit before ordering
- Function and sector: match the required anchor, steaming, stern, port/starboard, bi-color, or tri-color function.
- Required performance: confirm the certification and visibility distance required for your vessel; brightness alone does not establish compliance.
- Physical fit: compare the mounting footprint, fastener pattern, lens orientation, and available clearance.
- Electrical fit: verify DC voltage, wiring, polarity, switching, and any photocell or multi-mode behavior.
