12-24V IP66 Marine LED Masthead Navigation Light 2NM | Boat Kayak Stern Signal Lamp

IP66 Marine LED Masthead Navigation Light 12-24V for Boats Under 12m This marine LED masthead navigation light is engineered for reliable night signaling on small boats, kayaks, pontoons, and fishing vessels operating in coastal or inland waters. Designed with a fully sealed IP66 housing and stable 12-24V DC input range, it provides consistent white light visibility up to 2 nautical miles while withstanding spray exposure, vibration, and UV conditions common in marine environments. Production Description: Reliable navigation visibility in harsh marine conditions The SM2YB3 masthead light uses a high-strength PA GF engineered plastic housing combined with a precision-molded PC lens. This construction helps resist impact, salt corrosion, and long-term UV degradation. A brass alloy internal light hood improves thermal stability and maintains consistent light projection during extended night operation. Designed for compliance with marine navigation standards With a 225-degree light arc and 2 nautical mile visibility range, this LED masthead lamp supports safe vessel identification in accordance with COLREGS signaling requirements for vessels under 12 meters. The integrated LED module delivers stable luminous output across voltage fluctuations common in small boat electrical systems. Fully sealed structure for outdoor marine use Unlike traditional bulb navigation lamps requiring frequent maintenance, this LED navigation light features a sealed enclosure that reduces moisture ingress risks. It is suitable for open deck installations where spray, washdowns, or sudden weather changes may occur. Low power consumption for battery-dependent vessels The efficient 5W LED light source minimizes current draw, helping extend operational time on kayaks, canoes, and small fishing boats using limited battery capacity Technical Specifications Model Visibility Level arc Bulb Shell color Waterproof level Size   Weight SM2YB1 Green starboard light 1nm 112.5 Led 5W 12-24VDC Black IP66 90* 105mm 0.53KG SM2YB2 Red port light 1nm 112.5 Led 5W 12-24VDC Black IP66 90* 105mm 0.53KG SM2YB3 Masthead light 2nm 225 Led 5W 12-24VDC Black IP66 90* 105mm 0.53KG SM2YB4 Stern light 2nm 135 Led 5W 12-24VDC Black IP66 90* 105mm 0.53KG Typical Applications Small recreational boats Kayaks and canoes Pontoon boats Coastal fishing vessels Tender boats Inland watercraft Masthead vs stern vs port/starboard navigation lights Navigation lights serve different signaling roles depending on vessel position and movement. Masthead lights project forward and help define vessel heading, while stern lights indicate trailing direction. Port and starboard lights assist other vessels in determining right-of-way during night navigation. Understanding proper light positioning helps reduce collision risk in low-visibility environments. FAQ Is this masthead light suitable for kayaks and small boats? Yes. Its low power draw and compact sealed design make it suitable for vessels under 12 meters operating in inland or coastal waters. Does it require frequent bulb replacement? No. The integrated LED module offers longer service life compared with traditional incandescent navigation lamps. Can it withstand heavy spray or rain exposure? The IP66 sealed housing helps protect internal components from spray, washdowns, and outdoor marine conditions. What voltage systems does it support? It operates across a wide 12-24V DC input range commonly used in small marine electrical systems. Why is light arc coverage important? Correct arc angles help other vessels interpret your heading and movement, improving nighttime navigation safety.
