Buying Guide
What should you consider when buying 12V marine courtesy lights?
- Waterproof rating: Choose IP67 or IP68 for decks, transoms, and submerged exposure notes. IP67 protects against immersion in up to 1 meter for 30 minutes; IP68 allows deeper or longer submersion depending on model.
- Voltage and current: Ensure compatibility with your boat’s 12V electrical system. Some lights support a wide range (10V-30V) for universal use across vessels.
- Brightness and size: Consider lumen output per light and housing size to fit your mounting area and desired visibility.
- Mounting style: Surface-mount vs. recessed vs. hidden mounts affect aesthetics and wiring layout. Include screws or mounting kits if provided.
- Durability: Look for ABS or corrosion-resistant housings and PC lenses to withstand saltwater, rain, and vibration.
- Color options: White is common for utility lighting; RGBW adds mood lighting and signaling capabilities for certain applications.
- Installation practicality: Check hole size, mounting depth, and whether wiring routes are straightforward for your boat’s layout.
Practical installation tips
- Plan your light layout to minimize cable runs and balance illumination across decks or cabins.
- Use waterproof connectors and sealant around openings to preserve IP ratings.
- Test lights with a 12V supply before final mounting to confirm brightness and color options (RGBW models).
