You need a light source that will never, ever let you down and the UV Gear Tag is it! This rechargeable gear light will glow in the dark all night long and then recharge during the day by absorbing any light. It’s perfect for attaching to your backpack, bug-out bag or keys because it is lightweight, waterproof and completely reusable and reliable. Made of non-toxic materials, it will last forever because it never wears out and will work in any temperature! It will recharge with one minute of sunlight, 5 to 10 minutes of ambient light or just a few seconds of using a high intensity flashlight. Using the flashlight will make the crystals super bright. It will dim out over 12 hours and is bright enough for you to see it in the dark.
