A2 Automatic Lifejacket Light

When someone falls overboard, every second matters. In darkness or rough weather, locating a person in the water can be difficult, even when they are wearing a lifejacket. A flashing light helps make the wearer easier to spot and gives the crew a visual reference during a search and rescue operation.

The A2 lifejacket light is designed for this purpose. It uses an LED light source and a water-activated switch to provide automatic illumination when it comes into contact with water. There is no need for the wearer to manually switch the light on in an emergency.

How Does the A2 Lifejacket Light Work?

The A2 combines automatic water activation with manual switch-off. Once the water sensor is activated, the LED begins flashing at a frequency of 50–70 flashes per minute. The light produces a luminous intensity of at least 0.75 cd and is designed to operate for at least eight hours.

These features are important in man-overboard situations, where a visible signal can help the crew identify the person's position in the water, particularly at night.

The unit uses a built-in lithium battery, so the battery is not intended to be replaced by the user. With a stated service life of five years from the date of manufacture, the A2 also gives buyers a clear reference for stock management and replacement planning.

A Practical Choice for Marine Safety Equipment

For shipowners, shipyards and marine equipment distributors, choosing a lifejacket light involves more than checking its basic specifications. The activation method, lighting performance, certification and service life all need to match the intended application.

The A2 lifejacket light is available with CCS or EC certification, depending on the supplied version. Buyers should confirm the required approval and review the corresponding certificate before placing an order, especially when the equipment is intended for a vessel subject to SOLAS requirements.

Whether you are sourcing replacement lights for an existing fleet or purchasing life-saving equipment for a new vessel, confirming these details in advance helps avoid specification mismatches during procurement.
