ACR C-Light H2O Water-Activated Personal Distress Light, 20 Lumen LED, USCG/SOLAS Approved

The ACR C-Light H2O is a water-activated personal distress light built to help searchers spot you fast during a low-light emergency on the water. At its core is a 20 lumen white LED that runs continuously for more than 30 hours, giving you a long working window if you end up in the water or separated from your vessel. The light offers two ways to turn on: press the On/Off button manually, or arm it so it activates automatically the moment it contacts water. That automatic water-activation sensor means the light can start working even if you are unconscious or unable to reach the switch.

The case is impact resistant, slim, and lightweight, so it rides easily in a pocket, on a backpack strap, or attached to a life jacket. Mounting is flexible thanks to lashing loops built into the sides of the housing: use the included Velcro strap wrapped around the loops for a secure attachment point, or use the included PFD clip to slide the light directly over the oral inflation tube of an inflatable life jacket. A lanyard is also included for additional attachment options.

The C-Light H2O is tested waterproof for 24 hours at 3.3 feet and runs on two AA batteries (sold separately). It carries USCG/SOLAS approval along with CE and Transport Canada certification, making it a solid choice for boaters, paddlers, and anyone who wants a compact backup distress light on hand for life jackets, camping, biking, or vehicle emergency kits.
