{"product_id":"attwood-911490-1-navigation-light-pole-base-2-wire","title":"Attwood 911490-1 Navigation Light Pole Base 2-Wire","description":"\u003cp class=\"nvn-hero\"\u003eThe Attwood 911490-1 is the black plastic deck base your Attwood plug-in pole light seats into, not the light itself. It's a 2-wire combination base with two pins, a V-adapter, and 7-1\/2 inch hard wire leads, sized to fit the 5110, 5570, 5091 and 5300 Series lights. It gives you a clean, removable mount for a navigation pole light.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThis is the plug-in deck base your Attwood pole light drops into. It's the black plastic receptacle, not the light itself, and it does one job well. It gives you a clean, wired mounting point so a removable navigation pole light seats the same way every time. If you've ever fought a hard-wired pole light that had to come off for trailering or storage, you already know why a proper base matters. This is the fix.\u003c\/p\u003e\n\u003cp\u003eAttwood built this one as a 2-wire combination base. It carries two pins, a factory V-adapter, and about 7-1\/2 inches of hard wire lead coming off the bottom. That short pigtail is your splice point. You run it into the nav light circuit you already have, match positive to positive and negative to negative, and the pole light powers up as soon as it's seated. Simple.\u003c\/p\u003e\n\u003cp\u003eOne more note on the wiring. It's a 2-wire setup, so it's built for single-function lights and for bi-color heads that run off two conductors. Keep your polarity straight and use tinned, marine-grade wire for the run back to the switch. Heat-shrink the splice. Salt water finds every bare copper strand eventually.\u003c\/p\u003e\n\u003cp\u003eFitment is the thing to get right. This base is made for Attwood's plug-in pole light families: the 5110 Series frosted globe, the 5570 Series LED anti-glare navigation pole lights, the 5091 Series bi-color, and the 5300 Series anti-glare lights. If your light is one of those, the 2-pin pattern lines up and the pole locks in. Running the 5091 bi-color up front? Mount the base at a height where the light throws its red and green arcs the way it should, so you stay legal after dark.\u003c\/p\u003e\n\u003cp\u003eThe footprint is rectangular, 4-1\/4 inches long by 1-1\/2 inches wide. That flat rectangle sits nicely on a flat windshield frame, a squared-off gunwale cap, or a deck pad. On a rounded rail or a curved gunwale it can leave a small gap at the corners, so a lot of guys back it with a thin mounting plate or a couple of shims to spread the load and keep it from flexing. Fiberglass flexes too, so if you're bedding it into a thin deck, a backing plate underneath is cheap insurance.\u003c\/p\u003e\n\u003cp\u003eA couple of real-world install notes from folks who've wired plenty of these. First, the 7-1\/2 inch leads are short. They're meant to be a starting point, not a full run to the panel, so plan on splicing in tinned marine wire before you route through the deck. Second, those pins live outside in salt air. A dab of dielectric grease on the pins at install keeps corrosion from creeping in and saves you from the flicker that shows up a season later. Third, seat the pole squarely. If the 2-pin alignment is off, the pole can wobble in a chop, and nobody wants a nav light waving around at 25 knots.\u003c\/p\u003e\n\u003cp\u003eSome boaters like to add an inline 2-pin connector between the base leads and the boat wiring, so the whole pole and base assembly lifts out for cleaning or winter storage without cutting anything. That's optional, but it's a nice touch on a boat that gets trailered a lot.\u003c\/p\u003e\n\u003cp\u003eWho's this for? Anyone replacing a cracked or corroded base under an existing Attwood pole light, or anyone rigging a fresh nav light setup on a skiff, center console, or small cruiser. The black plastic keeps it low-key against dark rails and consoles. It ships in bulk packaging as the base only, so you'll pair it with the pole light you already run or buy separately. Keep in mind plastic bases can chalk or crack after a few hard seasons in strong sun, so if your boat lives on a lift in full exposure, check it now and then and swap it when it starts to look tired.\u003c\/p\u003e\n\u003cp\u003eBottom line: it's an honest, inexpensive part that fixes a common headache. Get the right light family, back it up on a flexy surface, grease the pins, and keep your polarity straight. Do that and it'll give you a solid, removable nav light mount for years.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003eFits Attwood 5110 Frosted Globe, 5570 LED Anti-Glare, 5091 Bi-Color and 5300 Anti-Glare pole lights, so one base covers the common Attwood plug-in nav light lineup\u003c\/li\u003e\n  \u003cli\u003e2-pin, 2-wire design with a factory V-adapter for straightforward positive and negative hookup\u003c\/li\u003e\n  \u003cli\u003e7-1\/2 inch hard wire leads give you a starting pigtail to splice into your existing nav light circuit\u003c\/li\u003e\n  \u003cli\u003eRectangular footprint, 4-1\/4 in long by 1-1\/2 in wide, mounts flat to a windshield frame, gunwale cap or deck pad\u003c\/li\u003e\n  \u003cli\u003eBlack plastic housing keeps it low-key against dark rails and consoles\u003c\/li\u003e\n  \u003cli\u003eShips in bulk packaging as the base only, so you install it with the pole light you already run\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized Attwood Marine reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eWhich Attwood lights fit this base?\u003c\/summary\u003e\n    \u003cp\u003eIt's made for Attwood's plug-in pole light families: the 5110 Series frosted globe, the 5570 Series LED anti-glare navigation pole lights, the 5091 Series bi-color, and the 5300 Series anti-glare lights.
