All Daniamant Lifejacket lights are designed to deliver, as a minimum standard, the 0.75cd output specification and 8 hour duration required by IMO SOLAS regulations.
 
The DAN WR2 is the automatic recessed version of the DAN W2. With a special fitting arrangement the light is completely embedded in a lifejacket with only the dome visable above the fabric. The light is specially designed for lifejackets used on passenger vessels with excavation or chute systems for mass evacuation of passengers.
