Overview

The Perko 0904DP0STS is a horizontal-mount bi-color bow light for replacement use on sail or power-driven vessels under 12 meters (39.4 ft.) in length. It is a 12V incandescent unit with a 10-watt bulb included, rated for 1 nautical mile visibility, and it draws 0.80 amps.

This fixture combines the red and green sectors in one housing at the bow, with a polished stainless steel top over a black polymer base. Gold-plated contacts and red and green lenses make it a practical fit for smaller boats that still use a conventional incandescent navigation-light setup.

Key features

• Horizontal-mount bi-color bow light for replacement use on sail or power-driven vessels under 12 meters (39.4 ft.)
• 1 nautical mile visibility for the combined red and green bow sectors
• 12V incandescent setup with bulb included, rated at 10 watts and 0.80 amps
• Polished stainless steel top with a black polymer base
• Gold-plated contacts with red and green lenses
• Uses #4 mounting screws

Compatibility and fit

This light belongs on the bow where a combined red and green fixture is required. It suits smaller cruisers, runabouts, center consoles, and sailboats that need to replace an existing incandescent bow light without changing the basic layout of the navigation-light system.

Because it is sold for replacement use, it makes the most sense on boats that already have a compatible mounting position at the stem or foredeck. Checking the available flat mounting area before installation is still worthwhile, especially on older boats with limited space at the bow.

Installation and setup

It mounts horizontally and uses #4 fasteners. As with any bi-color bow light, orientation matters: the red lens faces port, the green lens faces starboard, and the fixture should sit on the centerline so the correct sectors show while underway.

The included bulb keeps the setup straightforward for 12V systems already wired for incandescent navigation lights. For owners replacing a worn or corroded bow fixture, that helps keep the job focused on the light itself rather than turning it into a full rewiring project.

Materials and corrosion resistance

The polished stainless top and polymer base suit a bow location that sees spray, UV exposure, and routine washdowns. Gold-plated contacts are useful here because the bow is one of the first places on the boat to collect moisture and salt residue, and small electrical connections tend to show that wear early.
