The YBA1 lifejacket light activates automatically on contact with water and produces a bright flashing LED signal to help locate a person in the water. It suits all types of lifejackets and is even more visible on safety-orange jackets.
The unit runs on high-performance alkaline batteries — mercury-free, environmentally friendly and shippable by air as normal cargo. It is approved to SOLAS, MED, MER and USCG standards.
