Smaller than other approved lights, the HemiLight™ɜ features rounded edges to maintain the integrity of inflatable life jackets. Attachment loops accommodate up to 5 cm (2 in) 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 freshwater, and can be deactivated simply by pushing the red button. Installation is quick and easy (the HemiLight™ 3 can be retrofitted to almost any style life jacket in a matter of seconds).

Available in two configurations: the HemiLight™3 offers a basic strobe mode which can be activated either manually or automatically.
