These little safety lights are seriously bright for their size - I almost couldn't believe how much visibility they provide. The 4-pack is perfect for keeping one on your bike, one on your running gear, one on the dog's collar, and a spare. They have 5 different lighting modes including solid white, white strobe, solid red, red strobe, and this red-white flash pattern that really gets attention. The clip is strong enough to stay put on clothing or gear, and they include a strap mount for attaching to things like bike frames or backpacks. They're IP67 waterproof, so rain or sweat won't kill them, and they can apparently survive a 10-meter drop (haven't tested that personally, but they feel durable). The USB charging is so convenient - no more buying expensive button batteries. A full charge gives you up to 20 hours on the strobe setting, which is plenty for multiple runs or bike rides. I've had drivers actually give me more space when I'm running with these compared to when I just wear reflective gear. For the price, getting four rechargeable lights is a steal compared to what you'd pay for similar lights at sporting goods stores. If you exercise outdoors in low light conditions, these are a no-brainer for safety.
