The masthead light meets a 2 NM visibility requirement and is suitable for boats up to 12 m (39.4 ft), while the deck light uses a 12 V, 20 W halogen bulb to throw working light onto the foredeck and cockpit area.\u003c\/p\u003e\u003cp\u003eThis style of combo light is common on smaller sailboats and compact powerboats where you want a proper steaming light when motoring, plus a practical mast-mounted work light without adding another fixture. The housing is IPX4 rated for spray and rain, and the overall size is 7.5 in x 5.25 in x 2.875 in (about 191 mm x 133 mm x 73 mm).\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eTwo-in-one unit: 2 NM masthead (steaming) navigation light plus a deck floodlight for forward working light\u003c\/li\u003e\n\u003cli\u003e12 V system support, with a 20 W halogen deck lamp for on-deck visibility when handling sails or gear after dark\u003c\/li\u003e\n\u003cli\u003eVertical, side mount format intended for the forward side of a mast, with flexible mounting arms to suit different mast profiles\u003c\/li\u003e\n\u003cli\u003eIPX4 water resistance for typical on-deck exposure, including spray and rain\u003c\/li\u003e\n\u003cli\u003eStainless steel metal parts in the mounting and hardware for better longevity around saltwater\u003c\/li\u003e\n\u003cli\u003eCompact footprint for tight installations: 7.5 in x 5.25 in x 2.875 in (191 mm x 133 mm x 73 mm)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eInstallation and setup\u003c\/h6\u003e\u003cp\u003eMount the unit on the forward side of the mast (or another vertical surface) where the steaming light has a clear arc and is not blocked by sails, rigging, or deck structures. Aim the floodlight so it lights the foredeck without shining back into the cockpit or helm position, since glare can be more of a problem than a lack of brightness.\u003c\/p\u003e\u003cp\u003eUse proper bedding\/sealant at fasteners and cable pass-throughs, and support the cable run inside the mast so it does not slap or chafe underway. After mounting, confirm alignment at night at the dock so the deck light falls where you actually work.\u003c\/p\u003e\u003ch6\u003eElectrical and system integration\u003c\/h6\u003e\u003cp\u003eThe masthead light circuit and the deck flood circuit are wired separately, which lets you switch them independently at the panel. Plan your wiring so the steaming light ties into your navigation light switching, and the floodlight is on its own switched feed for deck work.\u003c\/p\u003e\u003cp\u003eOn boats where existing wiring is aging or undersized, this is a good moment to pull new tinned marine wire and heat-shrink your terminations. Keep connections protected from moisture in the mast base and any junction points.\u003c\/p\u003e\u003ch6\u003eCompatibility and fit\u003c\/h6\u003e\u003cp\u003eThis style of 2 NM steaming light is used on vessels up to 12 m (39.4 ft). Confirm your local requirements for when the masthead (steaming) light must be shown, and verify you have enough mounting area for the housing and cable routing based on the overall dimensions.\u003c\/p\u003e\u003cp\u003eIt is intended for 12 V installations. If your boat is 24 V, confirm bulb and wiring requirements before ordering so you do not end up with the wrong electrical setup.\u003c\/p\u003e\u003ch6\u003eUse on board\u003c\/h6\u003e\u003cp\u003eThis light makes sense for skippers who motor under power at night and also want a mast-mounted work light for sail changes, anchoring prep, docking lines, or checking the foredeck without juggling a handheld light. It is also a practical fit for small cruising sailboats where space on the mast and cabin top is limited.\u003c\/p\u003e\u003ch6\u003eMaintenance and care\u003c\/h6\u003e\u003cp\u003eRinse salt off the lens and housing with fresh water after heavy spray or washdowns, and check the mounting fasteners seasonally for tightness. If performance drops, inspect for corrosion at connections and replace bulbs with the correct type and wattage for this fixture.\u003c\/p\u003e","brand":"Hella Marine","offers":[{"title":"Default Title","offer_id":52269082017973,"sku":"QBP481963","price":74.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1298401_qbp481963.jpg?v=1771541759","url":"https:\/\/www.qualityboatparts.com\/products\/qbp481963","provider":"Quality Boat Parts","version":"1.0","type":"link"}
