A Li-battery lifejacket light is a safety device designed to be attached to a life jacket or personal flotation device (PFD). It is powered by a lithium-ion (Li-ion) battery, which offers advantages such as longer operating times, higher energy density, and lightweight compared to traditional batteries. These lights are typically rechargeable, providing extended illumination without frequent battery changes. They are designed to be durable, waterproof, and resistant to harsh marine conditions. All the lights meet the standard SOLAS 1974 and its amendment. You can rely on our products.
