Lithium Battery Life Jacket Light — IMPA 330143

This water-activated LED life jacket light is essential safety equipment for cargo ships, container vessels, tankers, offshore support vessels, and passenger ferries. Mounted directly on life jackets and immersion suits, it automatically activates upon contact with water, emitting a bright white flashing light that dramatically improves visibility during man-overboard situations, abandon-ship drills, and nighttime rescue operations. By providing reliable illumination without any manual switching, it helps crews and rescue teams locate survivors faster in dark or rough sea conditions.

Designed and manufactured in accordance with MSC.81(70), MSC.200(80), MSC.226(82), and MSC.323(89), the JHYD-1 model features a hermetically sealed, high-frequency welded housing that resists water ingress and corrosion in harsh marine environments. The gold-plated water-contact pins ensure dependable activation, while the energy-efficient LED delivers a luminous intensity greater than 0.75 cd with a flash rate of 50–70 flashes per minute for over 8 hours of continuous operation. Powered by a CR14250 lithium battery with an open-circuit voltage above 3 V and a 5-year shelf life, the unit draws only 80 mA during operation. Its transparent frosted top shell allows visual inspection of internal components without disassembly.
