The ACR HemiLight 3 is an automatic, water-activated LED survivor locator light designed to attach to almost any style of life jacket, making it a favorite among cruise lines worldwide.

The all-new LED illuminates automatically for 20+ hours when it comes into contact with either salt or fresh water, and it can be manually deactivated at any time by sliding the built-in switch to the off position.

Installation is quick and simple, and the light offers two configurations, allowing it to be switched into strobe mode either manually or automatically for maximum visibility during a rescue. Built with a marine tough design for years of dependable service, the HemiLight 3 meets both USCG and SOLAS requirements and carries MED SOLAS approval, making it suitable for commercial and recreational vessels alike. It is powered by a non-hazardous lithium battery rated for a 5 year life and is water tight to 10 feet, so it stands up to harsh marine environments without compromising performance when it matters most.

This locator light is intended for use on life jackets and personal flotation devices to help rescuers spot a person in the water quickly, whether in open ocean, coastal waters, or inland lakes.
