Perko 1684 LED Folding Vertical Mount Combination Masthead / White All-Round Light, For Sail or Power Vessels Under 20m, 12V, 3nm

Overview

The Perko 1684DP0CHR is a folding vertical-mount combination masthead and white all-round navigation light for 12-volt systems on sail or power vessels under 20 meters. It uses two separate LED light compartments and carries a 3-mile rating, which is the detail most owners check first when replacing a combo masthead and anchor light.

This model suits installations where one assembly needs to cover masthead lighting underway and a white all-round light at anchor. The vertical fold-down mount is useful when clearance matters, and the light can swing down 90 degrees in either direction along the plane of the attachment plate.

The housing combines a black polymer top and base, a clear polymer lens, a chrome-plated zinc alloy insert, and a 3/4 in. anodized aluminum tube. Overall height is 13-3/8 in., so it is worth checking against your current light location before ordering.

Key features

• Combination masthead and white all-round light with two separate LED compartments in one assembly.
• Certified for sail or power vessels under 20 meters (65.6 ft.) with 3-mile visibility.
• 12V LED system with low current draw at 0.2 amps and 2.2 watts per compartment.
• Vertical fold-down mount that swings 90 degrees in either direction along the mounting plate.
• 3/4 in. anodized aluminum tube with black polymer top and base, clear polymer lens, and chrome-plated zinc alloy insert.
• Gold-plated contacts for a cleaner electrical connection in a marine wiring environment.

Compatibility and fit

Mounting dimensions matter on this light. The base measures 2-1/4 x 5/8 in., mounting-hole centers are 1-5/8 in., and it uses #8 screws. Those numbers help you confirm whether it will line up with an existing mount or whether the surface needs new holes.

This light is a good match for boats under 20 meters that need masthead and anchor-light functions in one vertical assembly. It fits well on boats where keeping the installation compact matters and where a fixed pole would be awkward during storage or low-clearance handling.

Installation and setup

The fold-down mount includes flat and 45 degree V-type mounting adapters, along with a notch for through-base wiring. That gives a little more flexibility when the mounting surface is not perfectly flat or when you want a cleaner wire run into the structure.

When replacing an older incandescent combination masthead and all-round light, do not assume it will be a direct wire-to-wire swap at the switch. This LED version may require switch rewiring or the correct conversion approach, so it is worth checking the existing navigation-light circuit before starting the job.

Use on board

This setup makes sense for owners who want one light assembly to handle the masthead function underway and the white all-round function at anchor. It also suits refits where lower power draw matters, since each light compartment uses only 2.2 watts.
