Overview

The Attwood Marine NV4012SSG-7 is a vertical surface-mount starboard navigation light with a green lens, an oval stainless steel housing, 2 NM visibility, and an IP67 water-resistance rating.

It uses an LED light engine rated for 50,000+ hours and stays cool to the touch, which helps when the fixture is mounted where people work around the bow or pass close alongside the rail. The smaller footprint also makes it easier to fit on boats where space for sidelights is limited and a cleaner surface-mount installation matters.

This is the green starboard side light in a navigation-light setup, so it is intended for the starboard side of the vessel and for installations that need clear side-light definition at night. Sharper cut-off angles and the built-in tell-tale indicator make it easier to confirm the light is operating and aimed for proper side-light function.

Key features

• Green starboard navigation light with 2 NM visibility
• Oval stainless steel housing for vertical surface mounting
• IP67-rated construction for areas exposed to spray, rain, and washdowns
• LED light engine with 50,000+ hours of service life
• Cool-to-the-touch operation compared with hot-running bulb fixtures
• Color-indicated cores that make wiring identification easier during installation
• Sharper cut-off angles and tell-tale indicators for clearer setup and on-board checks
• 2 NM U.S.C.G. certified

Compatibility and fit

This light suits boats that need a dedicated starboard sidelight in a compact surface-mount format. The vertical oval housing works well where a low-profile stainless fixture is preferred over a bulkier side light, especially on boats where the mounting area is visible and finish matters as much as function.

It is a practical match for refits where an older sidelight is being replaced with an LED unit that takes up less room and cuts down on routine bulb changes. On boats that spend time in saltwater or sit outdoors between trips, the stainless housing and corrosion-resistant build are useful in exposed mounting positions.

Installation and setup

The color-indicated wiring cores help keep installation straightforward when tying the light into the boat's navigation-light circuit. The tell-tale indicator is useful during setup and later checks, since you can confirm operation quickly without having to walk forward and inspect the lens directly.

For owners who want a clean side-light installation on a center console, walkaround, small cruiser, or similar boat, this fixture makes sense where a vertical mount and a stainless finish are part of the plan. It is also a sensible replacement part for boats that already use separate port and starboard sidelights rather than a combined bi-color bow light.
