It is made for vertical side mounting on the port side, where the red light needs to show the correct sector while staying clear of glare and obstruction.\u003c\/p\u003e\u003cp\u003eThis series uses LED technology with a clear lens appearance when the light is not illuminated. Across the range, the light measures 4-1\/8 inches wide, 3-5\/8 inches high, and projects 2-1\/4 inches from the mounting surface, with #10 mounting screws specified for installation.\u003c\/p\u003e\u003cp\u003eVoltage and housing finish depend on the selected variant, with 12 Volt and 24 Volt options available for matching the vessel electrical system.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eRed port side navigation light with a 112-1\/2 degree visibility arc for correct sidelight coverage.\u003c\/li\u003e\n\u003cli\u003e2-mile USCG 2nm certified visibility for sail or power driven vessels under 20 meters.\u003c\/li\u003e\n\u003cli\u003eLED operation uses less than half the energy draw of standard lights, with low heat and long service life.\u003c\/li\u003e\n\u003cli\u003eAvailable in 12 Volt and 24 Volt versions to match common DC marine electrical systems.\u003c\/li\u003e\n\u003cli\u003eHousing choices include chrome plated brass with black polymer base, all white polymer, and all black polymer.\u003c\/li\u003e\n\u003cli\u003eClear lens appearance when off helps the fixture sit cleanly on the hull or cabin side.\u003c\/li\u003e\n\u003cli\u003eUses #10 mounting screws, with a 4-1\/8 inch width, 3-5\/8 inch height, and 2-1\/4 inch overall projection for fit checks before drilling.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eVariants\u003c\/h6\u003e\u003cp\u003eThe range varies by housing finish and nominal voltage. Housing options include chrome plated brass with a black polymer base, white polymer, and black polymer, with each finish offered for either 12 Volt or 24 Volt installations.\u003c\/p\u003e\u003cp\u003eThe light function and core mounting dimensions remain consistent across the listed configurations: red port sidelight, 2-mile visibility, 112-1\/2 degree arc, #10 screw size, 4-1\/8 inch overall width, 3-5\/8 inch overall height, and 2-1\/4 inch overall projection.\u003c\/p\u003e\u003ch6\u003eInstallation and setup\u003c\/h6\u003e\u003cp\u003eMount the red sidelight vertically on the port side, in the same athwartship plane and at the same height as the green starboard sidelight. For proper navigation light layout, the sidelights should sit at least 1 meter below the masthead light.\u003c\/p\u003e\u003cp\u003eRemove the lens assembly before mounting the base. Use round head or pan head screws with a 5 mm or #10 diameter, and do not use countersunk screws. After wiring, refit the lens assembly and tighten the mounting screw.\u003c\/p\u003e\u003ch6\u003eElectrical and system integration\u003c\/h6\u003e\u003cp\u003eSelect the variant that matches the vessel supply voltage. The 12 Volt version is rated at 4.65 watts with current draw under 0.31 amps, while the 24 Volt version is rated at 2.52 watts with current draw under 0.09 amps.\u003c\/p\u003e\u003cp\u003eObserve voltage and polarity when connecting the supply leads. Use cable sized to keep total voltage drop below 0.5 Volt on a 12 Volt installation or below 1 Volt on a 24 Volt installation; 1.5 mm2 or No. 16 AWG is the recommended minimum cable size.\u003c\/p\u003e\u003ch6\u003eUse cases on board\u003c\/h6\u003e\u003cp\u003eThis light suits refits and new installations where a dedicated red port sidelight is needed on a boat under 20 meters. The 12 Volt versions fit many small cruisers, fishing boats, and sailboats, while the 24 Volt versions suit vessels already built around a 24 Volt DC system.\u003c\/p\u003e\u003cp\u003eThe finish choice is mostly about the mounting surface and the look of the boat. Chrome plated brass with a black base fits bright hardware layouts, while white or black polymer housings blend more quietly into matching topsides, cabins, or console areas.\u003c\/p\u003e\u003ch6\u003eMaintenance and care\u003c\/h6\u003e\u003cp\u003eClean the light with fresh water and mild detergent. Avoid harsh chemicals and abrasive cleaners around the lens and housing, especially where salt, UV exposure, and regular washdowns are part of normal use.\u003c\/p\u003e","brand":"Perko","offers":[{"title":"Chrome Plated Brass With Black Base \/ 12 Volt","offer_id":52581920145589,"sku":"QBP502930-V3","price":425.99,"currency_code":"USD","in_stock":false},{"title":"White Polymer \/ 12 Volt","offer_id":52581920178357,"sku":"QBP502930-V5","price":321.74,"currency_code":"USD","in_stock":true},{"title":"Black Polymer \/ 12 Volt","offer_id":52581920211125,"sku":"QBP502930-V6","price":312.83,"currency_code":"USD","in_stock":true},{"title":"Chrome Plated Brass With Black Base \/ 24 Volt","offer_id":52581920243893,"sku":"QBP502930-V7","price":0.0,"currency_code":"USD","in_stock":false},{"title":"White Polymer \/ 24 Volt","offer_id":52581920276661,"sku":"QBP502930-V8","price":0.0,"currency_code":"USD","in_stock":false},{"title":"Black Polymer \/ 24 Volt","offer_id":52581920309429,"sku":"QBP502930-V9","price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1334662_qbp502930.webp?v=1780201546","url":"https:\/\/www.qualityboatparts.com\/products\/qbp502930","provider":"Quality Boat Parts","version":"1.0","type":"link"}
