Lifejacket Light · Life Jackets & MOB Equipment
The Firefly 3 Waterbug from ACR Electronics is a lifejacket light. The recorded values come from ACR Electronics' ABS product design approval record: visibility of 1 mile (1.6 km) to 2 miles (3.2 km), a flash rate of 60 +/- 10 flashes per minute and power from two 1.5 V cells. Whether a specific version also meets the SOLAS LSA Code has to be checked against its approval documents. A lifejacket light is fixed to a life jacket to make a person in the water visible at night; its battery has an expiry date that has to be checked and the light replaced or serviced before it passes.
