A good safety item, to have, at an affordable price
This unit features multiple mounting options to attach to your life jacket. It is a good, affordable, water-tight safety light to have. When manually turned on, it emits a continuous bright white light, making you more visible, in the event of going overboard. This unit requires 2 "AA" batteries, to power it. Battery life is very good, providing you use quality batteries. I strongly recommend adding the ACR 3764 auto-activation strobe light as well, to increase drawing attention to your position. Both of these of these unit are very affordable, easily attach to your life jacket and increase chances of being found quicker.
