The choice of cruise lines worldwide, the ACR auto hemilight3 flashing survival light attaches to almost any style life jacket to safely meet USCG, med and solos requirements. The hemilight3 is by far the smallest of all other life vest approved lights. Features rounded edges to maintain the integrity of inflatable life jackets. In addition, it has attachment loops that accommodate up to 5 CM (2 in) wide webbing and the marine tough design ensures years of useful service. Another thing about the hemilight3 is that it has a high-intensity flashing LED light automatically activates for 20+ hours when it comes in contact with salt or fresh water and can be deactivated simply by pushing the red button. Installation is quick and easy (the hemi light 3 can be retrofitted to almost any style life jacket in a matter of seconds).
