Buying Guide: Oval Marine Courtesy Lights
- Flush mount vs. surface mount: Choose flush mounts for clean lines and reduced snag risk; surface mounts are easier to install where space is limited.
- Waterproof rating: For exterior or underwater exposure, aim for IP67 or higher to resist moisture and salt spray.
- Material and finish: Stainless steel bezels resist corrosion; chrome reflectors boost brightness and safety visibility.
- Power and voltage: Most marine lights operate at 12V DC. Verify compatibility with existing wiring and fusing.
- Brightness and beam: Consider the number of LEDs, beam angle, and lens design (prismatic lenses improve light distribution).
- Installation space: Check hole size, mounting depth, and whether included hardware suits your surface (wood, fiberglass, or metal).
- Quantity needs: For decks and walkways, plan multiple fixtures to reduce shadows and create even illumination.
