It is an incandescent commercial navigation light with 3 nautical mile visibility and a 135° visibility arc, giving larger vessels the stern or towing signal coverage required for night operation.\u003c\/p\u003e\u003cp\u003eThis light is built around a black fiber-filled polycarbonate housing with pre-wired medium prefocus sockets and two 3-foot lengths of 16\/2-SO cable routed through watertight terminal tubes. The access cap is watertight for bulb changes and lens cleaning, which matters on working boats where spray, vibration, and routine service access are part of normal use.\u003c\/p\u003e\u003cp\u003eVoltage depends on the bulb installed, with 24V, 120V, and 220V bulb options available. Bulbs are not included, so the correct Perko medium prefocus bulb must be matched to the vessel’s electrical system before installation.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eCertified for use on vessels over 20 meters or 65.6 feet in length.\u003c\/li\u003e\n\u003cli\u003e3 nautical mile visibility with a 135° light arc for stern or towing applications.\u003c\/li\u003e\n\u003cli\u003eDouble lens configuration supports commercial navigation light setups where a spare lamp arrangement is needed.\u003c\/li\u003e\n\u003cli\u003eBlack fiber-filled polycarbonate housing handles exposed marine mounting locations without adding unnecessary weight.\u003c\/li\u003e\n\u003cli\u003ePre-wired medium prefocus socket arrangement helps simplify installation and future bulb replacement.\u003c\/li\u003e\n\u003cli\u003eIncludes two 3-foot lengths of 16\/2-SO cable through watertight terminal tubes.\u003c\/li\u003e\n\u003cli\u003eWatertight access cap allows rebulbing and cleaning without removing the entire light from the mounting location.\u003c\/li\u003e\n\u003cli\u003eHorizontal mounting with a 3\/8-inch mounting bolt, 17-1\/4-inch overall height, and 6-3\/4-inch lens height.\u003c\/li\u003e\n\u003cli\u003eBulb options support 24V, 120V, or 220V systems, with bulbs purchased separately.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eVariants\u003c\/h6\u003e\u003cp\u003eThis product is offered in two configurations for different vessel signaling needs.\u003c\/p\u003e\u003cp\u003eThe housing style, double lens construction, visibility distance, visibility arc, mounting format, cable arrangement, and bulb platform are consistent across the range.

This version is the yellow towing light configuration for vessels that need the aft-facing towing signal rather than a standard white stern signal.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eCompatibility and fit\u003c\/h6\u003e\u003cp\u003eThe 1366 series is intended for larger vessels over 20 meters, including commercial craft, workboats, towing vessels, and larger yachts that require navigation lights in this class. It mounts on a horizontal surface, so the installation area should provide a level mounting point, enough height clearance for the 17-1\/4-inch body, and a cable path that protects the wiring from chafe and standing water.\u003c\/p\u003e\u003cp\u003eBecause this is an incandescent fixture, system compatibility depends on selecting the correct bulb for the vessel’s voltage. The light can be used with 24V, 120V, or 220V bulb options, but the bulb is not supplied with the fixture.\u003c\/p\u003e\u003ch6\u003eInstallation and service notes\u003c\/h6\u003e\u003cp\u003eDuring installation, the light should be positioned so the 135° arc is not blocked by rails, davits, deck gear, antennas, or other equipment near the stern or towing light location. The supplied cable lengths and watertight terminal tubes give the installer a practical starting point for making protected connections inside the vessel structure.\u003c\/p\u003e\u003cp\u003eThe watertight access cap makes routine service more straightforward, especially on boats that operate at night or run in saltwater spray. Keeping the lens clean and using the correct medium prefocus bulb helps the light maintain the intended visibility pattern and range.\u003c\/p\u003e","brand":"Perko","offers":[{"title":"White Stern Light","offer_id":52581976015029,"sku":"QBP285108-V1","price":0.0,"currency_code":"USD","in_stock":false},{"title":"Yellow Towing Light","offer_id":52581976047797,"sku":"QBP285108-V2","price":830.35,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1334900_qbp285108.webp?v=1780201945","url":"https:\/\/www.qualityboatparts.com\/products\/qbp285108","provider":"Quality Boat Parts","version":"1.0","type":"link"}
