Perko 1125 Plug-In Mount Combination Masthead/White All-Round Light, 12V, 35-7/8 in, USCG 3nm, For Vessels Under 20 m

Overview

The Perko 1125DP4CHR is a 12V plug-in combination masthead and white all-round navigation light for sail or power driven vessels under 20 m (65.6 ft.) in length. It is USCG 3-mile certified and uses a deck-mount base with a 3-3/8" x 2-1/4" footprint, so it is easy to compare against an existing mount before you order.

This light uses two compartments in one assembly, giving you a forward masthead light and a white all-round light in the same pole unit. The overall height is 35-7/8", the pole rake is 16°, and the tube is 3/4" anodized aluminum, which are the details that usually matter most when replacing a damaged pole light or matching an existing installation.

The upper section combines black polymer with chrome plated zinc alloy, and the base is chrome plated brass with gold plated contacts. It is a stow-away plug-in type, so the pole can be removed when not needed, and the base stays on deck with its cover in place.

Compatibility and fit

This light suits boats that need a removable pole light rather than a fixed housing. The combination layout helps when you want masthead and all-round functions in one assembly, and the exact height, rake, and base size make it easier to check fit against the light already on the boat.

It is a sensible match for owners replacing an older plug-in Perko combination light or setting up a removable navigation light on a boat that is trailered, stored under a cover, or needs the pole out of the way at the dock.

Installation and setup

Before ordering, confirm the mounting surface can take the 3-3/8" x 2-1/4" base and that your system is 12V. The 16° rake and 35-7/8" height should also be checked against nearby canvas, rails, and any hardware that could block the light or make the pole awkward to remove.

The plug-in layout is useful on boats where a fixed light would be in the way between trips. Once the base is mounted, the pole can be fitted when needed for navigation lighting and removed again for storage.

Materials and corrosion resistance

The mix of black polymer, chrome plated zinc alloy, chrome plated brass, and gold plated contacts suits an exposed deck location where spray and weather are part of normal use. For a boat kept in saltwater, regular rinsing and a quick check of the contacts during routine maintenance will help keep the connection clean.
