Perko Combination Masthead and White All-Round Light, 12V, 3-Mile USCG, Plug-In, 45° Rake

Overview

The Perko 1123/1124 Combination Masthead and White All-Round Light is a 12V plug-in navigation light for sail or power driven vessels under 20 meters, or 65.6 ft, in length. It combines a masthead light for use while underway with a white all-round anchor light function in one removable pole-style fixture.

This light uses two separate compartments for masthead and anchor lighting, with 10 watt bulbs in each compartment and 3 nautical mile USCG-certified visibility. The 3/4" diameter anodized pole has a 45 degree rake, making the light suited for windshield mounting where a removable stow-a-way pole is preferred over a fixed light.

The range includes horizontal and vertical base layouts with different pole heights, so the buyer can match the fixture to the boat’s windshield angle, available mounting surface, and required light height above nearby structure.

Key features

• Certified for use on sail or power driven vessels under 20 meters, or 65.6 ft, in length.
• Combines masthead and white all-round anchor light functions in one plug-in pole fixture.
• 3 nautical mile USCG-certified visibility for navigation lighting compliance on applicable vessels.
• 12V operation with two included bulbs, rated at 10 watts for each light compartment.
• Two light compartments allow the fixture to function as a masthead light while underway and as an all-round white light while at anchor when wired correctly.
• Stow-a-way plug-in type pole can be removed when the boat is trailered, covered, stored, or used in tight spaces.
• Black polymer and chrome plated zinc alloy top with a chrome plated zinc alloy mounting base.
• Gold plated contacts help maintain the electrical connection at the removable plug-in base.
• Polymer adapter supports installation on flat or V-type 45 degree windshields.
• Uses #8 mounting screws and a 3/4" diameter anodized pole.

Variants

This product is offered in four configurations that vary by mounting orientation and vertical height. Fig. 1123 models use a horizontal mount, while Fig. 1124 models use a vertical mount.

The core light function, 12V operation, two-compartment masthead and anchor layout, 3 nm USCG-certified visibility, 3/4" diameter pole, 45 degree pole rake, and #8 screw size are consistent across the listed configurations.

• 1123DP1CHR: Horizontal mount with 11-1/4" vertical height. This shorter horizontal-mount version suits installations where the long axis of the base needs to run across the mounting surface and a lower pole height clears surrounding structure.
• 1124DP1CHR: Vertical mount with 12-1/2" vertical height. This shorter vertical-mount version is for layouts where the pole tubing runs parallel with the base and the boat has limited clearance above the windshield area.
• 1123DP2CHR: Horizontal mount with 20-1/2" vertical height. This taller horizontal-mount version raises the light farther above the mounting surface for better clearance over windshield frames or nearby deck hardware.
• 1124DP2CHR: Vertical mount with 22" vertical height. This taller vertical-mount version gives the highest light position in the range while keeping the same plug-in base style for removal and storage.

Installation and setup

The fixture is intended for windshield-area mounting and includes an adapter for flat or V-type 45 degree windshield installations. Before drilling, confirm that the chosen location gives the light an unobstructed arc and keeps the pole clear of canvas, rails, antennas, and folding hardware.

The electrical setup uses separate masthead and anchor light functions. When wired correctly, the rear light cannot be activated independently, which helps maintain the intended navigation light behavior while underway and at anchor.

Compatibility and fit

This light is a good match for small powerboats and sailboats under 20 meters that need a removable white navigation light assembly rather than a fixed masthead or hardtop installation. The plug-in pole format is especially useful on trailer boats, runabouts, center consoles with windshields, and boats that are covered or stored with limited overhead clearance.

Horizontal mount models use a base dimension of 2-1/4" x 3/4", while vertical mount models use a base dimension of 3/4" x 2-1/4". Checking the base orientation, pole height, and available wire routing before purchase helps avoid fit issues during installation.
