Smaller than other approved lights, the HemiLight 3 features rounded edges to maintain the integrity of inflatable life jackets. Attachment loops accommodate webbing of up to 2" in width. The light offers a basic strobe mode which can be activated either manually or automatically. 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. Once the sensor is wet and the light is on, the light will stay on unless manually deactivated. Installation is quick and easy, and the HemiLight 3 can be retrofitted to almost any style life jacket in a matter of seconds.
