It uses a black polymer housing with a clear lens appearance when the light is off, giving the installation a clean look on a mast, cabin front, or other approved masthead light location.\u003c\/p\u003e\u003cp\u003eThis light has a 225° visibility arc and is USCG 3 nautical mile certified, which are key details when replacing an older masthead light or matching navigation lighting to a vessel in this size class. The LED versions are available for 12 Volt and 24 Volt DC systems, with low current draw compared with standard incandescent navigation lights.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eWhite masthead navigation light for sail or power driven vessels under 20 meters, or 65.6 feet, in length.\u003c\/li\u003e\n\u003cli\u003eUSCG 3 nautical mile certification for required forward-facing masthead visibility.\u003c\/li\u003e\n\u003cli\u003e225° visibility arc for proper masthead light coverage when installed in the correct orientation.\u003c\/li\u003e\n\u003cli\u003eAll black polymer construction for exterior mounting where spray, UV exposure, and vibration are part of normal boat use.\u003c\/li\u003e\n\u003cli\u003eLED lens stays clear when the light is not illuminated, helping the fixture blend into the boat when not in use.\u003c\/li\u003e\n\u003cli\u003e12 Volt version draws less than 0.35 amps at 5.25 watts, while the 24 Volt version draws less than 0.20 amps at 5.6 watts.\u003c\/li\u003e\n\u003cli\u003eOverall size is 3-5\/8 inches high by 4-1\/8 inches wide, with a 2-1\/4 inch projection from the mounting surface.\u003c\/li\u003e\n\u003cli\u003eUses #10 mounting screws, making it practical for replacement work where the mounting surface and wiring route are already planned.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eVariants\u003c\/h6\u003e\u003cp\u003eThis masthead light is offered in two voltage configurations so it can match the boat’s DC electrical system without changing the basic light style.\u003c\/p\u003e\u003cp\u003eThe housing style, white masthead function, 225° visibility arc, USCG 3 nautical mile certification, and overall dimensions remain the same across these versions. The voltage, wattage, and current draw are the key differences to confirm before installation.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e0170BM0DP3: 12 Volt version. This version is for 12V DC navigation light circuits and draws less than 0.35 amps at 5.25 watts.\u003c\/li\u003e\n\u003cli\u003e0170BM0DP4: 24 Volt version. This version is for 24V DC navigation light circuits and draws less than 0.20 amps at 5.6 watts.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eInstallation and fit\u003c\/h6\u003e\u003cp\u003eBecause this is a masthead navigation light, placement and orientation matter. It should be mounted where the 225° forward arc is not blocked by rails, canvas, antennas, radar equipment, or the mast profile itself. On replacement projects, check the existing screw pattern, wire entry, and projection from the mounting surface before removing the old fixture.\u003c\/p\u003e\u003cp\u003eThe compact body works well on boats where a black fixture is preferred against dark trim, black mast sections, or windshield frames. For a clean installation, route and protect the wiring so it is not under strain and seal the mounting area in a way that suits the deck, cabin, or mast material.\u003c\/p\u003e\u003ch6\u003eElectrical and system integration\u003c\/h6\u003e\u003cp\u003eSelect the version that matches the vessel’s DC system: 12 Volt for standard 12V lighting circuits or 24 Volt for 24V systems. The LED draw is low, which helps reduce load on the navigation light circuit during night runs, anchorage approaches, early departures, or long passages where required lights stay on for extended periods.\u003c\/p\u003e\u003cp\u003eThis is a straightforward replacement or new-install light for owners, riggers, and service yards working on navigation lighting for boats under 20 meters. It is a good match when the installation calls for a white masthead light with a black polymer housing, LED operation, and verified 3 nautical mile visibility.\u003c\/p\u003e","brand":"Perko","offers":[{"title":"12 Volt","offer_id":52581976146101,"sku":"QBP122615-V1","price":640.68,"currency_code":"USD","in_stock":false},{"title":"24 Volt","offer_id":52581976178869,"sku":"QBP122615-V2","price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1334905_qbp122615.webp?v=1780201948","url":"https:\/\/www.qualityboatparts.com\/products\/qbp122615","provider":"Quality Boat Parts","version":"1.0","type":"link"}
