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 M3 low profile light is a single very compact flashing unit making the light less susceptible to damage during evacuation. It is fitted with clips and there are two versions to choose from, one to go over a thin strap (called clip 1) and one to go over a 5cm belt (called clip 2). The Daniamant M3 is the manual version of the Dan W3 lifejacket light.
