The Crewsaver lifejacket light mounts via a PVC loop around the base of the inflation tube. Its domed LED light was visible for about 270° when viewed from deck level, only being obscured by our casualty Fred’s head.
Its light was the bluest of all we tested, which gave it a sharp pinprick of illumination that was very easy to spot from afar, though its flash was slightly shorter than the longest-flash Spinlock light.

The water-sensitive switch activated by a dangling wire was among the most responsive on test. It could also be switched on and off via a push button.

However, the light is mounted in such a way that it would be inside the sprayhood if that was deployed, and would dazzle the wearer. Its battery is sealed inside the light unit.

We tested this light alongside 8 other incandescent, strobe and LED models. Read the reviews of other lifejacket lights on test.

The Crewsaver (inset) was brightest from a distance but was mounted low down on the oral inflation tube
