Overview

The Attwood Marine NV4012SSR-7 is a port-side LED navigation light with an oval housing and a vertical surface-mount layout for boats that use separate sidelights. It shows red to port, runs on 12V systems, carries a 2 nautical mile visibility rating, and uses an IP67-rated housing for wet, exposed locations.

This LightArmor light is suited to cabin sides, coamings, and other upright mounting faces near the bow where a separate sidelight is needed. The stainless steel housing and polycarbonate lens make sense on boats that live in salt, sun, and regular washdowns, while the LED light engine avoids the bulb changes that come with older incandescent fixtures.

Key features

• Port red LED sidelight for installations that use separate port and starboard fixtures
• 2 nautical mile visibility rating with U.S.C.G. certification
• Meets EN/ISO 19009:2015 requirements
• Vertical surface-mount oval housing for cabin sides, coamings, and other upright mounting faces
• Stainless steel housing with a polycarbonate lens for exposed marine service
• IP67 rating for spray, rain, and routine washdowns
• LED light engine rated for more than 50,000 hours and stays cool in use
• Color-indicated wire cores simplify wiring during new installs and refits

Installation and fit

This is a single red sidelight, not a bi-color bow light and not a starboard fixture. It belongs on the port side of the boat and is meant for a vertical surface mount, so it is a good match when the boat already uses individual port and starboard lights instead of a combined bow light.

Color-indicated wire cores help during wiring, which is useful on refits where access behind the mounting surface is limited. If you are replacing an existing side light, confirm that your mounting position gives the correct port-side arc and that your boat uses a 12V circuit for navigation lighting.

Use on board

This light fits well on center consoles, walkarounds, pilothouse boats, and small cruisers where the sidelight sits on an exposed vertical face and stainless trim matches nearby hardware. It also works well for owners updating an older incandescent side light to an LED unit with lower upkeep.
