Smaller than other approved lights, the HemiLight3 features rounded edges to maintain the integrity of inflatable life jackets. Attachment loops accommodate up to 5 cm (2″) wide webbing, and the marine tough design ensures years of useful service. The 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 HemiLight3 can be retrofitted to almost any style life jacket in a matter of seconds. 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 SOLAS requirements.
