Stay visible in the water and on land Visible from up to 5km away Waterproof to 100m Two modes - flashing and steady Up to 250 hours battery life in flashing mode Clips to Swim Secure products for added visibility Battery included Available in red, white and green The Adventure Lights Guardian Tag-It is the most durable safety light available on the market, which is why we have chosen it as the perfect addition to Swim Secure products. The mini carabiner makes it easy to attach the light to Swim Secure products. It can be clipped to the loops on Dry Bags, the rope on the Tow Float Pro and around the safety cap attachment on Tow Floats. It is visible from inside a Tow Donut and the phone pocket of the Window Dry Bag. The light is operated by twisting the domed lens, easy to do even with chilly fingers. To switch from flashing to steady mode simply remove the battery and replace it upside down. This light is super-strong - Swim Secure have run them over with a car and they continued working as if nothing had happened! You can see their test in the video below.
